What are the chemical symbol, formula, valency of the following:-
1.Sodium Sulphate2.Magnesium Hydroxide

Open in App

Solution

1. The valency of sodium (Na) is 1 and of sulphate (SO₄^2-) is 2. Hence, the formula of sodium sulphate is Na₂SO₄.
2. The valency of Magnesium (Mg) is 2 and of hydroxide (OH^-) is 1. Hence, the formula of magnesium hydroxide is Mg(OH)₂.
