Water requirements miscellaneous

  1. A synthetic sample of water is prepared by adding 100 mg Kaolinite (a clay mineral), 200 mg glucose, 168 mg NaCl, 120 mg MgSO4 and 111 mg CaCl2 to 1 litre of pure water. The concentrations of total solids (TS) and fixed dissolved solids (FDS) respectively in the solution in mg/L are equal to
    1. 699 and 599
    2. 599 and 399
    3. 699 and 199
    4. 699 and 399
Correct Option: A

Total solids = 100 + 200 + 168 + 120 + 111 = 699 mg/l
Fixed dissolved solids = 200 + 168 + 120 + 111 = 599 mg/l
Kaolinite is insoluble.
