Two samples of water A and B having concentration 16.2 pp m of `Ca(HCO_(3))_(2)` and 13.6 pp m of `CaCl_(2)` respectively. Then

A

Hardness is more in 'B' sample than in 'A'

B

Hardness is more in 'A' sample than in 'B'

C

Hardness is same in both cases

D

Hardness in sample 'B' is twice that of the sample 'A'

Text Solution

Verified by Experts

The correct Answer is:
A
A = 16.2 g of `CaHCO_3`
B = 13.6 g of `CaCl_2`
hardness of `A = 16.2 xx 100/162 = 10` ppm
hardness of `B = 13.6 xx 100/111 =12.25` ppm
