"Copper
in moist air slowly acquires a dull green coating. The green material is
a 1:1 mole mixture of Cu(OH)2 and CuCO3:[1]"2Cu(s) + H2O(g) + CO2 Copper carbonate decomposes at high temperatures, giving off carbon dioxide and leaving copper(II) oxide. CuCO3g(s) |

Following
the filtration of the solution, the filtrate is dried under vacuum to
produce magnesium carbonate as a hydrated salt:Mg2+ + 2HCO3- ? MgCO3 + CO2 + H2O When dissolved with acid, magnesium carbonate decomposes with release of carbon dioxide: MgCO3 + 2HCl ? MgCl2 + CO2 + H2O MgCO3+ H2SO4 ? MgSO4 + CO2 + H2O |
