Question

find the formula and valency of ferric ion​

Answer 1

Answer:

The valency of an element is always a whole number. Some elements exhibit more than one valency, i.e., they have variable valency. In Iron [II] sulfate or ferrous sulfate, i.e., FeSO4, the valency of iron is two. In Iron [III] sulfate or ferric sulfate, i.e., Fe2(SO4)3, the valency of iron is three
