Common Anions and Cations Lab
Common Anions and Cations Lab Period 3 The purpose of this lab was to identify common anions and cations in solutions using simple chemical tests, and to use the results discovered in these tests to identify ions in an unknown solution. First we tested for anions, skipping the boiling bath described by step one; we tested for the chloride ion. To do so we added 2 mL of sodium chloride to a clean prepared test tube. To a second clean test tube we added 2 mL of the unknown substance-A102. One mL e

Stoichiometry and the Chemical Equation
Stoichiometry and the Chemical Equation (Reaction of Hydrogen Peroxide and Bleach) Purpose and Method: When hydrogen peroxide, H2O2(aq), is mixed with bleach, active ingredient, NaOCl(aq), oxygen gas is formed, O2(g). Based on the amount of reactants used and the amount of product(s), determine the stoichiometry of the chemical reaction. Running two sets of reactions; SET A where the amount of bleach is held at a constant 4.0mL; secondly SET B where the amount of H2O2(aq) is held at a constant
