The Formula of the Nitride of a Metal X is Xn, State the Formula of : Its Sulphate Its Hydroxide. - Chemistry

The formula of the nitride of a metal X is XN, state the formula of :

Answer in Brief

The formula of nitride of metal X is XN

Since valency of nitrogen is 3-

∴ Valency of X is 3+

(i)

Sulphte of metal

`"X"^{3+}["SO"_4]^{2-}` = ⇒`"X"_2["SO"_4]_3`

(ii)

The hydroxide of metal X

`"X"^(3+) ["OH"]^-1` = = `"X"_1["OH"]_3 = "X[OH]"_3`
