    200 mg/L and 0 mg/L
  • c)
    250 mg/L and 50 mg/L
  • d)
    250 mg/L and 0 mg/L
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
A water sample analysis produces alkalinity and total hardness of 200 ...
Concept:
Carbonate hardness = minimum of {Alkalinity, Total Hardness}
Total hardness = Carbonate Hardness + Non-carbonate Hardness.
Calculation:
Carbonate Hardness= minimum of {200 mg/L , 250 mg/L}
Carbonate Hardness = 200 mg/L as CaCO3
Non-Carbonate Hardness = Total Hardness – Carbonate Hardness
= 250 – 200
= 50 mg/L ​as CaCO3

Analysis of Water Sample

Alkalinity and total hardness of a water sample are given as 200 mg/L and 250 mg/L as CaCO3, respectively. We need to determine the carbonate and non-carbonate hardness (as CaCO3) of the water sample.

Calculation

The total hardness of the water sample is the sum of carbonate and non-carbonate hardness. Therefore,

Total hardness = Carbonate hardness + Non-carbonate hardness

250 mg/L = Carbonate hardness + Non-carbonate hardness

We know that alkalinity is due to the presence of bicarbonates, carbonates, and hydroxides of calcium and magnesium. Therefore, the alkalinity of the water sample is equal to the carbonate hardness.

Alkalinity = Carbonate hardness

200 mg/L = Carbonate hardness

Substituting the value of carbonate hardness in the above equation, we get

250 mg/L = 200 mg/L + Non-carbonate hardness

Non-carbonate hardness = 50 mg/L

Therefore, the carbonate and non-carbonate hardness (as CaCO3) of the water sample will respectively be

Carbonate hardness = Alkalinity = 200 mg/L

Non-carbonate hardness = Total hardness - Carbonate hardness = 250 mg/L - 200 mg/L = 50 mg/L

Hence, the correct answer is option 'A'.

A water sample analysis produces alkalinity and total hardness of 200 ...
Carbonate Hardness= 200 mg/l
Non-Carbonate Hardness= 50 mg/|


formula:- Total Hardness(TH) = Carbonate +NonCarbonate Hardness

Carbonate = (alkalinity , TH) minimum of these
