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 then in 'A'

B

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

C

Hardness in same in both cases

D

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

Text Solution

Verified by Experts

The correct Answer is:
A
`A=16.2g of CaHCO_(3)`
`B=13.6g of CaCl_(2)`
hardness of `A=16.2xx(100)/(11)=12.25` ppm
