Ion of element 'X' combines with sulphide ions and forms ${XS}_{3}$ . What is the valency of 'X'?

Open in App

Solution

${XS}_{3}$ contains one cation of X and three $S^{2 -}$ ions.

Valency of one $S^{2 -}$ = 2
Valency of three $S^{2 -}$ = 2 x 3 = 6

The compound ${XS}_{3}$ is overall neutral in charge. So, the valencies of the ions must be balanced while writing the chemical formula.

Therefore, the valency of 'X' is 6.
