Glauber Salt test

Glauber Salt test

Test process :

1.      First normal water hardness test. (Suppose 28 ppm.)

2.      Make 8% Glauber salt solution . Than test the solution hardness . (Suppose 36 ppm.)

3.      Than compare between water hardness and solution hardness.

Formula :

Glauber salt hardness = 8% Na₂SO₄ solution hardness – Water hardness.

 Such as : 36-28=8 ppm.

The salt is good.

If the salt hardness above 15ppm it will be not allowed.

Normally the salt hardness range is 4-15 ppm.
