b) Give reason why the water to be supplied for Zeolite process must be free from Fe2+ and Mn2+ ions. A zeolite softener was used to remove the hardness of 95,000 liters of hard water completely. The softener required 475 liters of NaCl solution containing 18 g/liter of NaCl for regeneration. Calculate the hardness of hard water in ppm.
