Question

cross cross method of cupric sulphate​

Answer 1

Answer:

- To use the cris’s cross method the absolute value of the oxidation number of the first ion is used as the subscript of the second.

The subscripts are then reduced by the greatest common factor.

The chemical formula compound by Cris’s cross method of copper sulphate is CuSo4 where the valency of Cu is 2 and valency of So4 is 2.

So after criss cross method the formula is Cu2(So4)2.
