Net Ionic equation:

Explanation / Answer

Ans 1 :

First we start by completing the molecular equation :

K2SO4 (aq) + SrI2 (aq) = SrSO4 (s) + 2KI (aq)

The aqueous species are split into their respective ions , and then the spectator ions are cancelled out from both the sides of quation , to get the net ionic equation as :

Net ionic equation :

Sr2+ (aq) + SO42- (aq) =SrSO4 (s)
