Question

How to calculate equivalent weight of copper sulphate?

Answer 1

For ionic salts we take the amount of charge present on an ion (cation or anion) to be the n factor, we have equivalent mass of CuSO4 as 159.609/2 = 79.804 gm/mol.

Answer 2

Answer: Equivalent weight of copper sulfate is 80.

Explanation: Equivalent weight is the ratio of molecular weight to the positive charge on cation.

${\text {Equivalent weight}}=\frac{\text {Molecular weight}}{\text {Positive charge on cation}}$

For $CuSO_4$: Charge on Copper :+2

Molecular weight of $CuSO_4$= 160g/mol

${\text {Equivalent weight}}=\frac{160}{2}=80$
