Answer 2

Answer:

alkaline = Hardness is the sum of the multivalent metal ions in solution, whereas alkalinity is a measure of the solution's ability to neutralize acids (sum of hydroxide, carbonate, and bicarbonates). In natural water systems calcium carbonate is usually present and responsible for different characteristics of the water.
