15000 litres of hard water was passed through a zeolite softener. The exhausted zeolite required 120 litres of NaCI having stream of 30g/l of NaCL Calculate the hardness of water.
Calculate the total hardness in ppm in given water sample.
: 50ml of standard hard water , containing 1mg pure CaCO3 per ml consumed 20ml EDTA solution.
: 50ml of water sample consumed 30ml EDTA solution using EBT indicator.
Ten thousand litres of hard water was made soft with zeolite. The exhausted zeolite required a total amount of 8 lit of NaCl solution containing 150 gm per litre for regeneration. Calculate the hardness of water.
