Question

Write balanced net in ionic equation for the reactions that occur in each of the following cases. identify the spectator ion or ions in each reaction. Always put the cation first and the anion second. For the not ionic equations type your answer using the format Ga3+(aq) + 3OH-(aq) rightarrow Ga(OH)3(s) for Ga^3+(ag) + 3 OH^- aq) rightarrow Ga(OH)_3(s). Pb(NO_3)_2 (aq) + Na_2SO_4 (aq) rightarrow net ionic equation spectator ions CuBr_2 (aq) + NaOH (aq) rightarrow net ionic equation spectator ions AgNO_3 (aq) + KI (aq) rightarrow net ionic equation spectator ions

Explanation / Answer

a) net ionic equation:   Pb+2 (aq)   + SO4-2 (aq) -------------------> PbSO4 (s)

spectator ions :   Na+ , NO3-

b) net ionic equation : Cu+2 (aq) + 2OH- (aq) --------------------> Cu(OH)2 (s)

spectator ions :   Na+ , Br-

c) net ionic equation   : Ag+ (aq)   + I- (aq) ------------------> AgI (s)

spectator ions : K+ , NO3-
