Short Note

The valencies (or charges) of some of the ions are given below :

Ion            Valency        Ion                Valency                        (Charge)                             (Charge)

Sodium ion       1+      Nitrate ion            1–  
Copper ion       2+       Sulphide ion         2–

Using this information, write down the formulae of :

  1. Sodium sulphide
  2. Copper nitrate
