In the simplest terms, what is hardness?

Explanation:
Hardness is the dissolved minerals in water, mainly calcium and magnesium, that give water the ability to use up soap. These ions react with soap to form scum and reduce how much foam you get, so water with more hardness “consumes” more soap. That’s why it’s described as the soap-consuming power of water. It isn’t about color, taste, or acidity—those are different properties. Hardness can be temporary (due to bicarbonates, which can be boiled off) or permanent (from other calcium/magnesium salts).
