In the making stock solutions from solids problem, make a 100 ml solution that is 1.0 M of the Cl- ion using NaCl and make a 100 mL solution that is 0.7 M of the Cl- ion using MgCl2. Also make a 250 ml of a solution that is 0.34M in sodium cation, using sodium sulfate decahydrate. And 500ml of a solution that is 0.25M in sulfate anion, using sodium sulfate decahydrate. Give details about the equipment used, which solutions you mixed together, and amounts of each.
