the valency of silicate ion is 4-
The formula for a sulphate ion is SO42- so the valency of a sulphate ion is -2.
The formula for a chromate ion is CrO4-2, and its charge is -2.
The sulfite ion has a valency of 2.
The chromate ion (CrO4-2) has yellow colour so all the chromate compounds including silver chromate is yellow in colour.
The chromate ion is CrO42-
the valency of silicate ion is 4-
The formula for a sulphate ion is SO42- so the valency of a sulphate ion is -2.
