2 thoughts on “Why presence of calcium bicarbonate in water give rise to temporary hardness in water but presence of sodium bicarbonate does not.”
Explanation:
Temporary hardness is due to the presence of calcium hydrogencarbonate Ca(HCO3)2(aq) and magnesium hydrogencarbonate Mg(HCO3)2(aq). … This removes the calcium ions or magnesium ions from the water, and so removes the hardness. Therefore, hardness due to hydrogencarbonates is said to be temporary.
