%, determine its degree of saturation.

Water analysis was carried out for a groundwater sample. The sum of the anions is equal to the sum of the cations. Calculatea) Total hardnessb) Carbonate and Non-Carbonate Hardness Hardnessc) Alkalinity

Note: Read the question carefully and give me right solution according to the question. I want clear solution with clear steps. A water contains 38.50 mg/L as CaCO3 of carbon dioxide, 288.00 mg/L as CaCO3 of Ca2+ and 53.00 mg/L as CaCO3 of Mg2+. All of the hardness is carbonate hardness. Using the stoichiometry of the lime soda ash softening equations, what is the daily sludge production (in dry weight, kg/day) if the plant treats water at a rate of 56.00 MGD? Assume that the effluent water contains no carbon dioxide, 30.0 mg/L as CaCO3 of Ca2+ and 10.0 mg/L as CaCO3 of Mg2+. Be sure to calculate the mass of CaCO3 and Mg(OH)2 sludge produced each day.

Write down The composition and typical properties of the more commonly occurring clays such as Illite.

4) Calculate the amount of water necessary for slaking a quicklime obtained from a 1000 kg limestone with 5% (by weight) impurities. Is this amount larger or smaller than is necessary for a quicklime obtained from a pure limestone? (Ca:40, C:12, O:16, S:32, H:1)
