Purpose: We already knew that the chemical properties of each pure substance are not are not changed after separation in a mixture. The key to find a physical property that one part of the mixture does have but the parts of the mixture doesn’t. In magnetism a magnetically susceptible material is extracted from a mixture depending on a magnetic force. Filtration is separation of an insoluble solid and a liquid. Filtration depends on solubility, the filtrate is the one want to keep (liquid) and the residue on the filter paper is the solid (we may or may not want to keep depending on the experiment). Evaporation is the separation of a liquid and a soluble liquid. In evaporation the solution is heated to the boiling point for the liquid to evaporate. …show more content…
Iron is an element because it has one type of atom and it can be found on the periodic table by itself .That salt (Na+Cl) is a compound because it has two types of atoms and both atoms/elements can be found on the periodic table separately. That magnetic means attractive force to a magnet and, that Iron powder is magnetic. Magnetism is a physical property because it is a reversible property and it can be observed without changing the substance into something new. Solubility is the ability to dissolve in water and salt is able to dissolve in water. Solubility is a physical property because its reversible, it changes in size and shape, and it can be observed without changing the substances without changing the substances to form a new one. In this investigation, we wanted to …show more content…
What physical properties did you observed in each of the components (iron, salt, and sand) of the mixture? I observed the physical property of magnetism in the iron powder and the physical property of solubility in sand (insoluble in water) and salt (soluble in water).The magnetism attracted the iron powder to the magnet and, since the salt is soluble in water it got filter out with the water, but the sand didn’t get filtered out because it insoluble in water.
2. How did these physical properties help you to separate the components of the mixture (including the name of the each method)? The magnetism helped separate the iron powder because the iron powder has the property of magnetism. The iron powder stuck to the magnet in the plastic bag. The property of solubility helped separate the salt and sand because salt can dissolve in water, while sand cannot. So the salt filter out with the water but since salt is insoluble it didn’t get filtered out. The property of solubility helped separate the water from the salt too, by evaporation.
3. Did any of the components share other similar physical properties (e.g. states of the matter. size. shape, color, texture, etc.)? Yes the components share other similar properties like their sate of matter they are all solids (the iron powder, salt, and

    The neutralization of the reaction was verified using pH paper to test whether the pH was neutral or slightly basic. At this point, the two possible products in the round bottom flask could have been exo- and endo-norborneol. Extraction and washing was performed and the exo- and endo-norborneol products formed were extracted into dichloromethane due to their similar solubilities, where the two products are overwhelmingly non-polar despite the one hydroxyl group. The dichloromethane (DCM) was the bottom layer formed, while the aqueous layer, the layer that was washed away, was the top and this was due to the weight of the chlorine atom that made DCM more dense. Extraction was repeated several times due to the partition coefficient, as it theorizes how smaller extractions are better than bigger extractions because they yield more concentrated extractions in the end.…

    As the reactants don’t contain a single reactive element, the reaction cannot be single displacement. Thus, the reaction is a double displacement. Double displacement reaction is a chemical reaction, in which the positive ions of two different chemical compounds exchange and produce two new compounds. In the reaction, Calcium and magnesium element of two compounds exchange, forming the calcium sulfate and magnesium chloride. I noticed that during the reaction, some white powder is produced and starts precipitating at the bottom of the test tube.…

    Starting out, there was a mixture of an unknown acid, base, and neutral component. Just like the process outlined in the introduction, a solvent would be added to the solution containing the acid, base, and neutral unknown mixture. This solvent must have specific characteristics regarding solubility such that it dissolves the substance desired to be extracted while not dissolving or dissolving in only small portions the other substance not wanted purified out. It should also be easy to separate from the compound left in it after purification of the other so that complete purification can take take place4. This is why diethyl ether was used because it is a hydrocarbon, meaning it is mostly insoluble in water and satisfies the requirements discussed.…

    Ionic compounds are able to dissociate into ions and, the ions are able to carry charge through the solution (water). The relative melting point of Sodium Chloride and Potassium Bromide were tested two different ways, expressing that Sodium Chloride and Potassium Bromide have a relatively high melting point. Sodium Chloride and Potassium Bromide were first tested by putting a candle underneath a sample of the compounds. The compounds did not melt which told us that they did not have a low melting point. Sodium Chloride and Potassium Bromide were then tested by putting a Bunsen Burner…

    IONIC LIQUIDS Introduction:- Ionic liquids are actually salts that are liquid in state, normally referred to compounds that have melting point below an arbitrary temperature i.e. 100° C. Unlike some other ordinary liquids like water and gasoline, that are composed of neutral species while ionic liquids are composed of ionic species and ionic intermediates commonly known as “ionic fluids” and “liquid electrolytes”. In ionic liquids there is a species that has a delocalized species and the other species may an organic species or an inorganic species. The term "ionic liquid" in the general sense was used as early as 1943. They are powerful solvents and electrically conducting fluids.…

    Calorimetry allows for the heat of the solution to be calculated since the heat capacity of the calorimeter is known and the change in temperature is observed. The heat capacity is the ability for the container to retain the heat the is produced or absorbed without allowing for the outside environment to impact the reaction. This closed system allows for easy calculations where q_rxn+q_water+q_calorimeter=0. This is important to the lab that the total heat lost and gained must all equal zero. It would be hard to calculate how much heat was lost in the world by the experiment, so isolating the system to the calorimeter allows for the…

    Acid base titrations: A titration is the addition of a measured volume of one solution, from a burette, to an unknown volume/concentration of another solution until the reaction between then is complete. An acid base titration is carried out to determine an unknown concentration by using a solution of known concentration. An indicator is used to show a dramatic and rapid colour change, at the end point of the titration. Preparing a standard solution: The substance used for the standard solution must have a high degree of purity, preferably solid, because this is easier to measure (using a scale) and the substance can’t absorb water or release water. Oxalic acid and anhydrous sodium carbonate are used to make the standard solutions.…

    An ideal recrystallization solvent should have these properties: - The compound is soluble in hot temperature and insoluble in cold temperature. The difference in at hot and cold temperature is very important to the process. Because when the solvent is insoluble in hot temperature, it will not dissolve result in cannot be recrystallized. - There are two phases to identify the unwanted impurities: dissolved form present in solvent at normal temperature or undissolved form in higher temperature. Therefore, the impurities will be taken out using the hot filtration when dissolving the impure solids.…

    This is because the negatively charged oxygen atoms in the water molecules attract each of sodium ion and the positively charged hydrogen atoms attract on each of negatively charged chloride ion. Overall, the strength of many hydrogen bonds in the water molecules pulls the ions apart and keeps them dissolved. As well as that, hydrogen bonds also form between water molecules and polar molecules so water easily dissolves polar molecules. However, hydrogen bonds do no form between water molecules and non-polar molecules as they are hydrophobic and because hydrogen bonds have no interactions. The versatility of water as solvent also allows it to serve as the medium of transport for so many…
