Answer #1

we have below given equation

2 NaI (aq) + H2SO4 (aq) --> 2 HI (g) + Na2SO4 (aq)

Complete ionic equation is

Spectator ions should not be removed here. Spectator ions are part of total ionic equation

2 Na+ (aq) + 2 I- (aq) + 2 H+ (aq) + SO42- (aq) --> 2 HI (g) + 2 Na+ (aq) + SO42- (aq)

Spectator ions should be removed now. Spectator ions are not part of total ionic equation

After removing Spectator ions, net ionic equation is:

I- (aq) + H+ (aq) --> HI (g)
