WebAnswer (1 of 2): Temporary hardness consists of the bicarbonates of calcium and magnesium. Heating water to 100 C decomposes the soluble bicarbonates to the carbonates, according to: Ca(HCO3)2 = CO2 + H2O + CaCO3, and similarly for Mg(HCO3)2. Both MgCO3 and CaCO3 are insoluble and precipitate o...
