Solution

1. The formula for nitrate is NO₃^-Hence its valency is 1.As the velency of metal is 2, therefore on cross multiplying the valency of two we get M(NO₃)₂2. The formula of NO₂^-Hence its valency is 1As the velency of metal is 2, therefore on cross multiplying the valency of two we get M(NO₂)₂
