Copper sulfate is also used to test blood for anemia. The blood is tested by dropping it into a solution of copper sulfate of known specific gravity – blood which contains sufficient hemoglobin sinks rapidly due to its density, whereas blood which does not sink or sinks slowly has insufficient amount of hemoglobin.

Copper Sulphate is commonly used by gardeners and commercial farmers to prevent problems with fungus or mold The copper status of the soil, together with the frequency of application and quantity of copper sulfate applied, will determine the effects of copper sulfate on plants.

Used in an area of copper-deficient soil, copper sulfate enriches the soil and provides an essential nutrient to growing plants. When soil is copper-deficient, young plants may develop chlorosis, a condition in which leaves yellow due to lack of chlorophyll. Copper deficiencies can also cause stunted or atypical growth; young plants in very nutrient-deficient soil may simply die. Wilting, lack of flowers and reduced fruit harvest are all likely effects of copper-deficient soil. Copper sulfate prevents these problems. Test soil regularly, and apply copper sulfate as needed in a spray or fertilizer preparation.

Various Applications of Copper Sulphate:
 

• Agriculture: Technical Grade Fungicide used for making of Bordeaux Mixture
• Industrial : It is largely used as Textile mordant and also used in Electroplating and Dyes Intermediate
