Question

How do you test for hydrogen sulfide in the water ?

Answer 1

The test for hydrogen sulfide(${\mathrm{H}}_2\mathrm{S}$) in the water is as follows:

1. The preliminary test for hydrogen sulfide(${\mathrm{H}}_2\mathrm{S}$) is its smell and taste. It gives a pungent smell and can cause olfactory desensitization in humans.
2. Hydrogen sulfide(${\mathrm{H}}_2\mathrm{S}$) is in gaseous form and can easily vaporize and leave the water, hence appropriate laboratory techniques are required to perform the task.
