Solution
Ans 3 :
The molecular equation is given as :
Al 2 (SO 4 ) 3 (aq) + 3CaCl 2 (aq)Â Â = 3CaSO 4 (s) + 2AlCl 3 (aq)
the ionic equation is given as :
2Al +3
(aq) + 3SO 4
2-
(aq) + 3Ca 2+
(aq) + 6Cl -
(aq) = 3CaSO4 (s) + 2Al +3
(aq) + 6Cl -
(aq)
The net ionic equation will be given as :
3Ca 2+
(aq) + 3SO 4
2-
(aq) = 3CaSO 4 (s)
