1.	What is the most efficient method to get water with zero degrees hardness?(a) Electrolysis(b) Permutit process(c) Synthetic resins(d) Calgon processI have been asked this question in a national level competition.Origin of the question is Hydrogen in chapter Hydrogen of Chemistry – Class 11
Answer» Correct choice is (b) Permutit process The explanation: Permutit is hydrated SODIUM aluminum SILICATE, it exchanges it’s sodium ions for DIVALENT ions of calcium and magnesium, permutit when fully exhausted can be REGENERATED by treating with 10% of sodium chloride solution. It is the most efficient method to GET water with zero degrees of hardness.
