Water Hardness - Department of Chemistry
For example, when hard water is heated, Ca 2+ ions react with bicarbonate (HCO 3-) ions to form insoluble calcium carbonate (CaCO 3), as shown in Equation 1. (1) This precipitate, known as scale, coats the vessels in which the water is heated, producing the mineral deposits on your cooking dishes.
Magnesium (Mg) and water - Lenntech
Water solubility of magnesium hydroxide is 12 mg/L. Other magnesium compounds are clearly more water soluble, for example magnesium carbonate (600 mg/L). Magnesium sulphate adds a bitter flavour to water, and has a water solubility of 309 g/L at 10 o C.
Reacting Carbon Dioxide with Lime water | Superprof
