Significance of Copper Sulfate

Copper Sulphate

Copper sulfate is an inorganic compound with chemical formula CuSo4. Pentahydrate is the most common form of copper sulfate, which is bright blue in color. Because of this characteristic CuSo4 is also known as blue vitriol and bluestone. It is mainly used in the agriculture industry, manufacturing hair dyes and for manufacturing leather products.

What color is CuSo4?

Its color ranges from grayish white in powder from to blue color in the form of crystal which is because it is called bluestone. It is in the form of salt that is used as pesticides, herbicides, and fungicides. It is an element that rarely occurred naturally but is moreover-man made. The largest copper sulfate crystals were 153.88 pounds which were grown by German students.

Properties of CuSo4

  • CuSo4 decays faster before melting

  • After heating it losses 2 molecules of water

  • It is produced by leaching low-grade copper ore in air

  • It gets hydrated in the air and absorbs water vapor

  • Hydrated CuSo4 has five water molecules

  • It reacts with metals to make Cu and metal sulphate.

  • It forms a blue-green color when it is heated


Why CuSO4 dissolves in water?

CuSO4 dissolves in water as water is a polar solvent. When the molecules those are solvent and have a charge that is unequally distributed in the molecule it is called as a polar solvent. In water, the oxygen atoms have a partial negative charge and the hydrogen atoms have a partial positive charge.CuSo4 is ionic in nature, CuSo4 separates into positively charged copper ions and negatively charged sulphate ions. The rate of polarity in water leads to the become a negatively charged when copper ions are attracted to oxygen atoms in water and become positively charged when sulfate ions are attracted to hydrogen atoms in water.

Industrial application

  • Copper sulfate is used in metal industry as an electrolyte in refining copper for copper coating steel wire.

  • Copper sulfate is also utilized in the synthetic fiber industry for the production of raw material for textiles.

  • Paint industry uses it as anti-flouring paints and plays a vital role in painting glasses.

  • It is used for the preparation of Bordeaux and Burgundy mixtures which is utilized as a fungicide in the agriculture industry.

Is CuSo4 an acid or base?

CuSo4 is a salt of Cu(OH)2 which is a strong bas; a strong base and weak acid results in the compound to become salt.

Copper sulfate in the environment

As copper sulfate dissolves in water easily, it can reach the environment easily. It is also found in soil which is useful for the plants. Too much of copper in soil may lead to environmental toxicity which is indeed toxic to plants which it inhibits photosynthesis. Copper sulfate in soil tends to bind organic matter. uses cookies to ensure that we give you the best experience on our website.
