Question

in a water sample co3 ions =90 mg/l Hco3 ions= 61 mg/l what is alkalinity of the water sample in mg/l​

Answer 1

Answer:

200 mg/l

Explanation:

CO3 = 90 mg/l

HCO3 = 61 mg/l

OH = 0

Total Alkalinity ( TA ) =0+90×50/30 + 61×50/61 = 200

Eq. Wt. Of CACO3 = 50

Eq. Wt. Of OH = 17

Eq. Wt. Of CO3 = 30

Eq. Wt. Of HCO3 = 61
