1. Nws yog npaj los ntawm cov tshuaj tiv thaiv ntawm magnesium oxide thiab hydrochloric acid. Cov tshuaj sib npaug ntawm cov tshuaj tiv thaiv yog:
MgO+2HCl====MgCl2+H2O
2. Nws yog npaj los ntawm cov tshuaj tiv thaiv ntawm magnesium carbonate thiab hydrochloric acid. Cov tshuaj sib npaug ntawm cov tshuaj tiv thaiv yog:
MgCO3+2HCl=MgCl2+CO2↑+H2O
3. Nws yog npaj los ntawm cov tshuaj tiv thaiv ntawm magnesium sulfate tov thiab barium chloride tov. Cov tshuaj sib npaug ntawm cov tshuaj tiv thaiv yog:
MgSO4+BaCl2=MgCl2+BaSO4↓
