The AQUASOL water test kit for sulphate is based on titrimetry and is extremely user friendly.
To determine the amount of sulphide present in the sample by titrimetric method. Principle. Sulphides often occur in ground water especially in hot springs, in wastewater and polluted waters. Hydrogen sulphide escaping into the air from sulphide containing wastewater causes odour nuisance.

There are several tests for sulfate ion to identify from other anions in qualitative analysis. Some of metal sulfate compounds are soluble in water and some metal sulfates form precipitates. Sulfate compounds of several d block metal cations form colours.
SULFATE TEST. The principal problem potential posed by sulfate ions in water is the possibility of calcium sulfate scale formation. Precipitation of calcium sulfate can occur when high concentrations of both calcium and sulfate exist simultaneously.
This water chemistry calculator calculates the ppm of all the important brewing ions based on the water volume and the mass of the salts you add. Enter a number for each salt you want to add (under the Mass Added column) choose the units that you want to use and click Calculate.
In weathering or contact with aerated water, the sulfides are oxidized to yield sulfate ions which are carried off in the water. Sulfate is carried to bodies of water by rain and through solution of sulfate compounds in sedimentary geologic formations within the drainage basin.
