Which reaction involves both neutralisation & precipitation?
Ca(OH)2 + CO2 -> CaCO3 + H2O
NaOH+ HCL -> NaCl + H2O
BaCl2 + Na2SO4 -> BaSO4 + 2NaCl
Pb(NO3)2 + 2KI -> PbI2+ 2KNO3

Ca(OH)2 + CO2 → CaCO3 + H2O = Neutralisation and Precipitation
NaOH+ HCl → NaCl + H2O = Neutralisation
BaCl2 + Na2SO4 → BaSO4 + 2NaCl = Double displacement
Pb(NO3)2 + 2KI → PbI2+ 2KNO3 = Double displacement and precipitation
