Question

Write the symbol and valency of bisulphite.

Answer 1

Bisulfite ion is formed by the combination of hydrogen ($\mathrm{H}$) and sulfite (${\mathrm{SO}}_3$).

Step-by-step explanation:

The symbol of Hydrogen is '$\mathrm{H}$', having a valency of 1⁺.

The formula of sulfite is ‘${\mathrm{SO}}_3$’ with valency 2^-.

Step 1 –Write the formula of bisulfite:

Symbol Valency

Hydrogen $\mathrm{H}$ 1⁺

Sulfite 2^-

Step 2 –Calculating the net valency

The net valency of bisulphite = 1 + (-2) = -1

The symbol of bisulfite is ${{\mathrm{HSO}}_3}^{-1}$and has valency -1.
