Learn How To Turn Hard Water Into Soft Water

The video tutorial explains the challenges of using soap in hard water due to calcium ions forming scum. It introduces washing soda as a cost-effective alternative to soften water by precipitating calcium ions. The video also covers the chemical changes when boiling water to remove temporary hardness and the use of ion exchange resins to exchange calcium ions with sodium ions, effectively softening the water. Finally, it describes a method to measure water hardness using soap solution.
