Alkalinity of water, in equivalent/litre (eq/litre), is given by

where, { } represents concentration in mol/litre. For a water sample, the concentration of HCO-= 2 x 10-3 mol/litre, CO2-3 = 3.04 × 10–4 mol/litre and the pH of water = 9.0. The atomic weights are : Ca = 40; C = 12; and O = 16. If the concentration of OH and H+ are NEGLECTED, the alkalinity of the water sample (in mg/litre as CaCO3), is
  • a)
    65.2
  • b)
    50.0
  • c)
    100.0
  • d)
    130.4
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Alkalinity of water, in equivalent/litre (eq/litre), is given bywhere,...
Alkalinity of water sample is due to presence of
[HCO3] and [CO32–]
Total alkalinity = 1 mole of [HCO3] + 2 mole of [CO32–] in terms of CaCO3
= (2 × 10–3 × 50 + 2 × 3.04 × 10–4 × 50) × 103 mg/l
= 130.4 mg/l as CaCO3
