Answer 2

Valency of Cu(NO3)2

The compound Cu(NO3)2 consists of copper (Cu) and nitrate (NO3) ions. To determine the valency of Cu(NO3)2, we need to consider the charges of the ions involved.

Copper (Cu) is a transition metal and can exhibit different valencies. In the case of Cu(NO3)2, the copper ion has a valency of +2. This means that each copper ion in Cu(NO3)2 carries a charge of +2.

The nitrate ion (NO3) has a fixed valency of -1. This means that each nitrate ion in Cu(NO3)2 carries a charge of -1.

Since the compound Cu(NO3)2 is electrically neutral, the sum of the charges of the copper and nitrate ions must balance out. Therefore, we need two nitrate ions to balance the charge of one copper ion with a valency of +2.

In summary, the valency of Cu(NO3)2 is +2 for the copper ion and -1 for each nitrate ion.
