Double displacement reaction → ions swap


Step 1: Complete balanced equation


Complete reaction: HCl (aq) + Li2CO3 (aq) → H2CO3 (aq) + LiCl (aq)

  • All Group 1A salts → soluble (aq)
  • Li and H → Group 1A
    • But H2COunstable decomposes
      • H2CO3 (aq) → H2O (l) + CO2 (g) 


Balanced reaction: 2 HCl(aq) + Li2CO3(aq)  → H2O (l) + CO2 (g)  +  2LiCl (aq)


Step 2: Total or full ionic equation

Breaks up into ions in solution:

  • soluble ionic compounds 
  • aqueous compounds 


  1. Li2CO3(aq) → 2Li+ (aq)+ CO32- (aq)
  2. HCl (aq) →  2H+ (aq) + 2Cl- (aq)
