A double displacement reaction is a type of reaction in which two reactants exchange ions to form two new compounds. Here are some examples of this type of reaction:
- AgNO 3 + NaCl → AgCl + NaNO3
- BaCl2 (aq) + Na2S4 (aq) → BaSO4 (s) + 2NaCl(aq)
- 2NaCl + CaSO4 → Na2SO4+ CaCl2
- H2SO4 + 2LiOH⇌ Li2SO4 + 2H2O
- AgNO3 + HCl ⇌ AgCl + HNO3
- Pb(NO3)2 + 2NaCl ⇌ 2NaNO3+ PbCl2
- HCl + NaOH → NaCl + H2O
- Al2(SO4)3 + 6NH4OH → 2Al(OH)3 + 3(NH4)2SO4
