Analyzing and Purifying Water: Required Practical Activities in Chemistry

The video tutorial covers a series of experiments to analyze and purify water. It begins with measuring the mass of dissolved salts in seawater using an evaporating basin. The concentration of salts is calculated by comparing the mass before and after evaporation. The tutorial also explains how to determine the pH of water samples using a pH meter or universal indicator solution. Finally, it demonstrates the distillation process to obtain potable water, highlighting the importance of low salt concentration and appropriate pH levels.
