Question

The hardness of water is 10 ppm it can be expressed in degree Clark as​

Answer 1

Concept:

Temporary hardness is the type of water hardness that may be eliminated by simple chemical or boiling operations. This kind of hardness is also known as carbonate hardness.

Permanent hardness is the hardness in water that cannot be eliminated by simple chemical or boiling treatments. This form of hardness is also known as non-carbonate hardness.

Given:

The hardness of water = 10 ppm ​

Find:

The hardness of water is 10 ppm it can be expressed in degree Clark as​?

Solution:

1) ppm (Parts Per Million) or mg/L

• 1ppm = 10⁻⁶

• 1 mg in 100 ml = 1 ppm

2) Degree Clark (0 Clark)

• 1 ppm = 0.070 Clark
• 10 ppm = 10 mg/L = 10 F = 0.70 Clark

Hence, The hardness of water is 10 ppm it can be expressed in degree Clark as​ 0.70 Clark.
