Copper Sulphate
Primarily used for agricultural purposes such as pesticide, germicide, feed additive, and soil additive. Some of its secondary uses are as a raw material in the preparation of other copper compounds, as a reagent in analytic chemistry, an electrolyte for batteries and electroplating baths, and in medical practice as a locally applied fungicide, bactericide, and astringent.
