In this video we will test samples of water for water hardness.
Water hardness is caused by the presence of calcium and magnesium ions in the water. Hard water will not lather (form bubbles) easily when mixed with soap but soft water will.
If you have any questions please leave a comment and I will get back to you as soon as possible.
