## Calculation of caco3 equivalents, Chemistry

Assignment Help:

Q. Analysis of water gave the following results H2SO4 = 196Mg/L; MgSO4 = 24Mg/L, CaSO4 = 272Mg/L and NaCl = 25Mg/L. Water is to be supplied to the town of the population of one lake only. The daily consumption of water is 50 Litre per head. Calculate the cost of the cost of Lime soda required for the softening of hard water for town for the month of April 2002. If the cost of lime is Rs.5/-per Kg and soda is Rs.8/-per Kg.

Ans. Calculation of CaCO3 equivalents

 constituent amount multiplication CaCO3 equivalent Requirement H2SO4 196 100/98 196*100/98 = 200 Mg/L L + S MgSO4 24 100/120 24*100/120 = 20 Mg/L L + S CaSO4 272 100/136 272*100/120 = 20Mg/L S NaCl 25 - Does not create hardness -

Amount of Lime required: = 74/100[H2SO4 + MgSO4]*Vol. Of water

= 74/100[200 + 20]*50*100000

= 814*106 mg = 814 kg/day

Amount of soda required: = 106/100[H2SO4 + MgSO4 +CaSO4]*Vol. Of water

= 106/100[200 + 20 + 200]*50*100000

= 2226*106

= 2226Kg/day

Cost of lime and soda for the month of April 30 days

Cost of lime = 814*30*5 = Rs. 122100

Cost of soda = 2226*30*8 = Rs. 534240
