Water hardness

Water hardness is a value that reflects the amount of dissolved calcium, magnesium, and iron salts in water. There is temporary hardness (that can be removed) and permanent hardness. Temporary hardness is caused by calcium and magnesium bicarbonates (Ca (HCO 3) 2 and Mg (HCO 3) 2 ), and permanent harness – by their sulfates ( (CaSO 4 and MgSO ...

Development of Porcelain Glaze from Recycled Calcium Carbide .

Calcium carbide reacts with water to produce acetelyne and calcium hydroxide according to the equation CaC 2 + 2H 2 O = C 2 H 2 + Ca(OH) 2, (Greenwood et al 1997). This reaction is the basis for the production of acetelyne gas used in oxyacetelyne welding. The waste by product consists mainly of Ca(OH) 2

Calcium Carbonate

The calcium carbonate level in swimming pools can be described as the average hardness of the pool water. The scale is basically the calcium carbonate which has already come out of its soluble form and then deposited itself on the pool surfaces. In case the level is too high, you can dilute the water through partial drainage of the pool and then replacing with a local and .
