Xcl2 Is the Chloride of a Metal X. State the Formula of the Sulphate and the Hydroxide of the Metal X. - Chemistry

XCl₂ is the chloride of a metal X. State the formula of the sulphate and the hydroxide of the metal X.

थोडक्यात उत्तर

Chloride of metal X is

By interchanging subscript and writing as superscript

The valency of metal X is 2

Valency of sulphate SO₄ is 2- and of hydroxide OH is 1-

∴ The formula of X²⁺ `"SO"_4^(2-)`

Sulphate of X = ⇒ XSO₄

The formula of hydroxide of a metal

X²⁺ OH^1- ⇒ ⇒ `"X"_1 ("OH")_2`

dropping 1 ⇒ X[OH]₂
