Report experiment 1: Preparation of laboratory solutions
In the first lesson of inorganic chemistry lab, preparing and testing solutions are two basic tasks needed to perform well. Dissolving a solid solute in the solvent or diluting the stock solution (a dilution series by using two techniques that are making parallel dilutions and serial dilutions) is to prepare solution with desired concentration of solute or desired volume. In practical part A, preparation of KMnO4 solution, students apply the formula for making parallel solutions to calculate the
