The two solutions were combined in a microwave tube and put in the microwave for 30 minutes at 80oC. The solvent was evaporated under reduced…
This then leads to the fact that the partial negative and positive parts of the water molecule can break the bonds of ionic and polar molecules which causes them to dissolve within the…
6.What are the various parts of a solution? There is the solvent which has the greatest abundance and there is the solute which is what is being dissolved. 7.Distinguish between an unsaturated, saturated, and supersaturated solution. Saturated is when it does dissolve in the solvent, supersaturated is when the solute does not dissolve in the solvent and unsaturated is when some of the solute dissolves in the solvent.…
Minoxidil, an antihypertensive vasodilator medication, which was developed in the 1950’s by a company called Upjohn originally used to treat ulcers. During their experiments with dogs, they figured out that it did not cure ulcers, but acted as a vasodilator. Due to this recent discovery, Upjohn was able to develop a compound called Minoxidil in 1963 as well as being able to synthesize over 200 variations of the compound. The molecular structure and compound of Minoxidil is C9H15N50, made entirely of nonmetals with the molecular weight being 209.2483 g/mol, the UIPAC name being 3 hydroxy, 2 imino, 6 piperidin, 1 ylpyrimidin, and 4 amine. The percentage composition of carbon being 51.65, hydrogen being 7.24, nitrogen being 33.47, and oxygen being 7.64.…
A solution is a homogeneous mixture of elements that are dissolved in water making it an aqueous solution. Solutions can form an acid, which is a substance that dissolves in water and gives a hydrogen ion, or proton (H+), to the water. It can also form a base, which is a substance that dissolves in water and…

The temperature that the solid compound begins to melt is known as the point of condensation and the point that the solid has completely liquefied is known as the melting point/temperature. Solubility is simply the ability of a solid compound to completely diffuse/dissociate in an aqueous solution. For example, when you add sugar to a glass of water and the sugar diffuses throughout the water, the sugar is said to be soluble in water. On the contrary, when you add oil to water and the oil settles on top of the water, the oil is said to be insoluble, or not soluble in…
Communication /6 Problem #2 Use the chart you just created to answer the following questions. a) Which substance would be the most corrosive? /1 Sample number 2 is the most basic and corrosive substance between the four samples.…
It occurs when there is non-volatile solute dissolved in a solvent. The presence of a solute lowers the temperature and makes the solution freeze. Most people use salt to melt snow, but what makes it melt the ice? In water salt is soluble. Salt is soluble because both salt and water have polar molecules.…
In the duration of this paper I will be describing the various aspects of what solutes and solvents are, and how there will be used during…
Research question How does red cabbage indicate the pH Level of different types of chemicals? Introduction A solution is a mixture of a soluble chemical dissolved in water. Think about the difference between salt water and tap water.…
Solubility - Fat was soluble in oil. Soap was not soluble in oil. Fat was not soluble in water.…
They were double replacement reactions which is the two products are interchanged to formed two new compounds on the reactant side. Intermolecular forces have heavy influence over solubility. Intermolecular forces are between molecules and are weak forces of attraction. There are four intermolecular forces including hydrogen bonding, dipole-dipole forces, dipole-induced dipole forces, and london dispersion forces. Hydrogen bonding is the strongest and occurs when one hydrogen molecule is attracted to another molecule.…
We believe that the temperature of the solvent, which in case is the water, played a role in the rate of dissolving. According to Middle School Chemistry, when the water has an increased temperature, it also has an increased molecular motion, which results in the fact that the molecules of the water and sucrose move and vibrate faster. Because of this, the water molecules were able to find and dissolve the sucrose molecules faster, which resulted in the increased rate of…
In today's generation wherein the advancement of technology takes its place in the busy world, everyone wants to get the things done in an instant. Before, people spend a whole day to do the laundry, particularly hand-washing. Today, it is common to do the laundry at home with the use of washing machines. But because everyone seems to be hungry of saving time, here comes many companies that offer dry cleaning and laundry services. Dry cleaning and laundry may seem to have the same function, but these two differ in so many ways.…
