Question

How to calculate TH of water
​

Answer 1

Answer:

$\huge\bold\red{AnsWer}$

TH = [Ca] + [Mg] + [Sr] + [Ba] + [Fe] + [Mn] + [Al] + Conversation rules to other units are given in the table below. The total hardness TH is used to classify aqueous solutions into four water-hardness categories.

Answer 2

Answer:

The pH of pure water is 7, the negative logarithm of 1 X 10-7. A neutral solution is one that is neither acidic nor basic. The hydrogen ion concentration equals the hydroxide ion concentration, and both equal 1 X 10-7 M. In a neutral solution, then, pH = pOH = 7
