Describe how a sample of Magnesium Chloride crystals could be made from Magnesium Carbonate (MgCO3) and dilute Hydrochloric Acid (HCl). Give the chemical formula for the process (4 Marks)
Add excess Magnesium Carbonate to dilute Hydrochloric acid (1 Mark)Filter solution (1 Mark)Heat the solution to evaporate the excess water, leave to cool (1 Mark)MgCO3 + 2HCl = MgCl2 + CO2 + H2O (1 Mark)
