Development of an Equation

Purpose: Investigate a chemical reaction using lab procedures and observations. Then, find a pattern of reactivity and explain the findings using a chemical equation and particle diagram. Procedure: Refer to: Department of Chemistry, The Ohio State University. “Development of an Equation.” General Chemistry 1210 Laboratory Manual. Vol. 2013-2014. Plymouth: Hayden-McNeil. 32-35. Data/Results: Part A: In the potassium iodide solution, I think there were potassium atoms as well as iodine atoms. In the lead nitrate solution, I think there were lead…

Extended Experimental Investigation

Abstract: Cold packs are based on the principle of endothermic reactions, which means a reaction that absorbs heat from the surrounding resulting in a temperature drop. Due to this temperature drop, cold packs have many benefits when it comes to injuries such as sprains and strains. It cools the local tissue and reduces bleeding, swelling and pain. It also aids in a speedy recovery. The most commonly used chemical in instant cold packs is ammonium nitrate which will be tested…

Chem 101 Lab Report 2

Mixtures are made up of substances or components. If the mixture is fairly uniform in composition, properties, and its overall appearance, it is homogenous. If the component parts are clearly separated, it is heterogeneous. In order to identify the components in a mixture, methods must be used to sort out the components. However, the same methods will not work for sorting all substances. Four different processes would be employed to sort soluble and insoluble components in the following experiment. Introduction…

Rate of Diffusion

To test the effect of molecular weight on the rate of diffusion, various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time, formation of a white ring occurred. The white ring, in fact, is a product of the reaction between the molecules of ammonia (NH3) and hydrochloric…

Qualitative Analysis Part 2 Anions

Chloride Solution + 0. 1M AgNO3 =white precipitate formed, very fine texture. Iodide solution + 0. 1M AgNO3 =yellow/white precipitate formed, cloudy texture. Silver Chloride + ammonium hydroxide = white precipitate forms, slowly begins to disappear. Adding HNO3 the reappearance of a white precipitate began, indicating the presence of the chloride. SO4 solution + 0. 5mL of BaCl2-CaCl2 = heated for about 10minutes, fine white precipitate throughout test tube. 5drops of 6M HCl + SO4 = no change indicating no…
