Solutions

Expert Solution

a. SrCl2(aq) + 2NH4F(aq) ----------> SrF2(aq) + 2NH4Cl(aq)

   Sr^2+(aq) +2Cl^(aq) + 2NH4^+ (aq) +2F^-(aq) ----------> Sr^+2(aq) +2F^-(aq) + 2NH4^+ (aq) +2Cl^-(aq)

a. 2NH4NO3(aq) + Sr(OH)2(aq) ---------------> 2NH4OH + Sr(NO3)2(aq)

2NH4^+ (aq) +2NO3^-(aq) + Sr^2+ (aq) +2(OH)^-(aq) ---------------> 2NH4^+ (aq) +2OH^-(aq) + Sr^+2(aq) +2(NO3)^-(aq)

b. 2H3PO4(aq) + 3Ba(OH)2 (aq) --------------> Ba3(PO4)2 (s) + 6H2O(l)

   6H^+(aq) +2PO4^3-(aq) + 3Ba^2+(aq)+6(OH)^- (aq) --------------> 3Ba^2+ (aq) +2(PO4)^- (aq) + 6H2O(l)

removal of spectator ions to get net ionic equation

   6H^+(aq)+6(OH)^- (aq) --------------> 6H2O(l) net ionic equation

c. K2CO3(aq) + 2CH3COOH(aq) -------------> 2CH3COOK + Co2(g) + H2O(l)

   2K^+ (aq) +CO3^2-(aq) + 2CH3COO^-(aq)+2H^+(aq) -------------> 2CH3COO^-(aq) +2K^+(aq) + Co2(g) + H2O(l)

removal of spectator ions to get net ionic equation

CO3^2-(aq) + +2H^+(aq) -------------> Co2(g) + H2O(l) net ionic equation
