Solubility

Analysis: A1 vs. E1: Solubility with water (H2O) This test consists of two hydrocarbons, a cyclohexane and a cyclohexene, being added to water to test their solubility. Both the cyclohexane and cyclohexene reacted the same way after the water water was applied. Each chemical stayed afloat of the water although the physical/qualitative properties remained unchanged. The insoluble nature of the results in this test can be explained through the “like dissolves like” notion, where only polar…

Tara Ghaemi 9/16/16 Chao Li 232 Recrystallization of Acetanilide Introduction In this experiment, acetanilide will be purified to remove its two impurities by utilizing dissolution, hot vacuum filtration, and recrystallization. Hot vacuum filtration is performed to separate the crystal from the solution that it is present in. Hot vacuum filtration works best for this experiment because it prevents the premature crystallization of the solute, and thus lets the extracted crystal be extremely…

your data) Solubility - Fat was soluble in oil. Soap was not soluble in oil. Fat was not soluble in water. Soap was soluble in water. Reasoning (why does the above piece of evidence support your claim?) The above piece of evidence supports my claim because it proves that in the same substance (H2O), fat and soap have different solubility. In fact, they are opposites in solubility - the fat being insoluble and and soap being soluble. According to Scientific Principle #6, “Solubility is…

Solubility Phosphates are not very water-soluble, thereby creating a limiting potential for plant-growth in marine ecosystems. This explains its encompassing effect on the surface of affected water system, as observed in the Watershed Nature Centre. In addition, this can be observed from the site as less quantity of phosphorus get dissolved in running water compared to the amount that eventually gets into the water column. Temperature: The water surface gets heated up by sunlight, increasing…

electron scales and take note of the mass. Place the beaker on the hot plate, but don’t turn the hot plate on. 2. Place a thermometer in the beaker of water and check the temperature. Make sure the water is at 20°C. 3. Select a solvent to test for solubility first; for the method, sugar (sucrose) will be tested first. 4. Using a spatula, add one scoop of sugar to the beaker 5. Stir the water and sugar with…

chemical compound forming. This experiment was done to determine the identity of the nine unknown solutions like color (physical trait), and chemical characteristics. Of course to determine the identity of this nine unknown solutions a sequence of solubility tests…

stones is dependent on the chemical nature of the stone, or precipitate. The solubility of precipitate, its concentration, and the presence of other chemicals are all characteristics that are related to the…

Salts and molecules have similar characteristics, and many differences whether we can tell by first looks or not. Testing these two only supports the differences, and many structural functions cause these differences. Since salts are ionically bonded, they have different properties and functions compared to the covalent bonded molecules. Salts have a ionic bond, and we can confirm due to their electronegativity. As you move from left to right on the periodic table you would notice that…

crystallize under such low temperature. In part II, the filtrate now contains more chloride and sodium ions, so NaCl is to be removed next. Since NaCl is the least soluble out of the four possible salts at the majority of temperatures, but does not change solubility very much with the change of temperature. Therefore, the best way to crystallize NaCl is by evaporation. Through evaporation, the concentrations of sodium ions and chloride ions increased. The concentrations of the ions were so high…

The unknown compound was composed of small, white crystals as shown in picture 1. The compound was completely odorless, which was tested by simply smelling the compound. Picture 1 (Unknown Compound): The solubility test of the unknown compound determined that the compound was soluble in water (H2O). The other known salts that were tested that were also soluble were all of the sulfates and NaCl. These were the only salts tested, because before this experiment it was determined by the flame test…
