Potassium Sulfate And Sodium Chloride Essay - 912 Words

Introduction A solution is a uniform mixture of two or more components. The components can be identified as solutes or a solvent. The solutes are the minor components of the solution, and they are what get dissolved. The solvent is the major component of the solution, and it does the dissolving. Solutions are measured in terms of solubility. Solubility refers to the maximum amount of solute that will dissolve in the solvent. When the maximum amount of solute has dissolved, the solution becomes saturated. In solving the solubility, two things must be known: the mass of the solute and the mass of the solution. Different techniques can be used to determine the solubility of a solution, such as filtration through paper cloth or evaporation by heat. In this experiment, the solubility was obtained through evaporation of the solvent by heat. Potassium sulfate and sodium chloride will used in solutions to test the solubilities at room temperature and approximately 40â„Æ'. Potassium sulfate will also be used in a solution to test the uncertainty of the experiment. Procedure K2SO4: Approximately 3.00 grams of K2SO4 and 50 milliliters of water were added to a 50 milliliter beaker and stirred until they were completely dissolved. Then an empty petri dish was weighed on an analytical balance and the exact mass was recorded. 20 milliliters of saturated K2SO4 solution were added to the petri dish and weighed on the analytical balance. The exact mass of the petri dish andShow MoreRelatedTop 10 Worst Dog Food Brands Essay1644 Words   |  7 PagesVitamin E supplement, animal fat preserved with mixed-tocopherols (form of Vitamin E) zinc sulfate, ferrous sulfate, potassium chloride, calcium propionate (a preservative), dried carrots, dried peas, L-Lysine monohydrochloride, choline chloride, manganese sulfate, niacin, copper sulfate, Vitamin B-12 supplement, calcium pantothenate, Vitamin D-3 supplement, Vitamin A supplement, calcium carbonate, menadione sodium, bisulfite complex (source of Vitamin K activity), biotin, thiamine mononitrate, garlicRead MoreEssay on Lab Report637 Words   |  3 PagesZegbe CHM111 Anita Mohan 03-11-2013 Experiment: Chemical reactions, and Equations Materials: 3 mL of copper(II) sulfate solution. 5 mL of 6 M HCl piece of zinc wooden splint test tube Bunsen burner 3 mL of zinc chloride solution. pentahydrate distill water Read MoreChemical Compounds And The Compounds2276 Words   |  10 Pagescompound is ionic. From there, a conductivity test proved that the unknown compound conducted 1.1 volts of electricity, meaning the compound contained both positively and negatively charged ions that move around to conduct the electricity. Potassium Sulfate has a solubility of 1 g in 8.3 mL of water, which matches with the results of the unknown being soluble in water (The Merck Index).

Two qualitative tests are conducted in this lab: one with KMnO4 and another using FeCl3. KMnO4 (potassium permanganate) is able to oxidize a double bond forming a 1,2-diol at room temperature. This tests for a presence of a double bond and a positive test is a color change from purple to brown. FeCl3 (iron (III) chloride) reacts with phenols, forming into chemical complexes with different colors. This tests for a presence of a phenol group and a positive testRead MorePaint Pigment Essay1445 Words   |  6 Pagesmeasured.

The environmental group suggested recipes for making the soaps and testing the soaps so they were safe to use. Soaps are made by hydrolysis, from sodium hydroxide (a polar carboxyl group), glycerol, and a fat or oil. Figure 1. Soap [6] A soap consists of the polar carboxyl group and the long chain of non-polar carbons.

We noticed fairly large, white granules that didn’t have a great tendency to stick to one another. These results can be viewed in Table 1. There was no noticeable odor to our compound, or any other visible identifiers. Sodium Chloride is an odorless, colorless solid that dissolves completely in water. Our results matched these properties. We then performed a solubility test, since we could narrow down our choices by whether or not our compound was soluble in water.

Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt, it is commonly used as a condiment and food preservative. [edit] Properties Thermal conductivity of pure NaCl as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K and decreases to 0.069 at 314
