Fe + CuCl2 → FeCl2 + Cu
Cu + FeCl2 → Fe + CuCl2
Na2CO3 + HNO3 → NaNO3 + CO2 ↑ + H2O
Na2SO4 + HNO3 → NaNO2 + H2SO45, Na2SO4 +
Ba(NO3 )2 → NaNO3 + BaSO4
NaCl + Ba(NO3 )2 →NaNO3 + BaCl2
NaNO3 + BaCl2 KHÔNG TÁC DỤNG ĐƯỢC
Mg(HCO3)2 + Ba(OH)2 = MgCO3 + BaCO3 + H2O
2NaOH + BaCl2 → Ba(OH)2 + 2NaCl
FeCl2 + NaOH → Fe(OH)2 + NaCl
NaOH + MgCO3 = Na2CO3 + Mg(OH)2
