Question

chemical formula of hard water​

Answer 1

Answer:-

The formula of hard water is same as that of pure water or soft water. It is H2O. The difference is that hard water contains calcium and magnesium salts in it.

Answer 2

Chemical formula of hard water​ is calcium hydroxide Ca(OH)2.

Explanation:

• Hard water is water with an plenitude of mineral substance, particularly calcium and magnesium.
• This mineral-rich water causes obliterating impacts on family machines and water hardness minerals stand up to disintegration and look for to return to a solidified shape.
• In this process, the compound calcium hydroxide, Ca(OH)2, is included to the difficult water.
• The calcium hydroxide, or "slaked lime," raises the pH of the water and causes the calcium and magnesium to accelerate into CaCO3 and Mg(OH)2.
