Question

question 2 (1 point)

1. which of the following is not the correct name for cuso4

i. copper (i) sulphate
ii. copper (ii) sulphate
iii. cupric sulphate
iv. cuprous sulphate
i and iv
ii and iii
ii and iv
i and iii

Explanation:

In \(CuSO_4\), the oxidation state of copper (\(Cu\)) is \(+ 2\). In the Stock system, it should be named copper (II) sulphate. The common name for copper (II) compounds is cupric. Copper (I) compounds are named cuprous. So, copper (I) sulphate (\(i\)) and cuprous sulphate (\(iv\)) are incorrect names for \(CuSO_4\).

Answer:

I and IV
