Chemical formula of hydrogen sulphide is h2s
But the symbol of sulphide is so 2-
3
So why is it written as a in the formula

Solution

Dear student,

In hydrogen sulphide the valency of hydrogen is +1 and the valency of sulphide is -2.
When it forms the chemical formula then to balance the -2 charge on sulphur is stabilise by +2 charge of two hydrogens.
The chemical formula becomes $H_{2} S$

Regards
