What is the difference between zinc sulfate monohydrate and zinc sulfate heptahydrate?

Zinc sulphate is a common inorganic chemical. It is a colorless or white crystal, granule or powder. Zinc sulfate exists in different forms depending on the temperature at which it is placed. Zinc sulphate monohydrate and zinc sulphate heptahydrate are the two most common forms we encounter, so what is the difference between them? Let me give you a brief introduction.

zinc sulfatesulphate monohydrate

Zinc sulfate monohydrate
Molecular formula: ZnSO4.H2O (containing one crystal water per molecule)

Zinc sulfate monohydrate has two states of zinc sulfate powder and zinc sulfate particles. The powder is mostly used for feed and fertilizer additives, and the particles are used for fertilizer. The zinc content is generally between 33% and 35%, the particle size is 2-4mm, the product is white, the specific gravity is 3.31, soluble in water, slightly soluble in alcohol, and insoluble in acetone. Same application range as zinc sulfate heptahydrate.

Zinc sulfate Heptahydrate

Zinc sulfate heptahydrate (zinc bismuth, antimony)
Molecular formula: ZnSO4.7H2O (containing seven crystal water per molecule)

Zinc sulfate heptahydrate is crystalline, so there is no powder or granules, but also for feed and fertilizer, but the content of zinc sulfate heptahydrate is lower than that of zinc sulfate monohydrate, between 21% and 22.5%. 1.97, melting point 100 ° C. It is easily weathered in dry air, soluble in water, insoluble in ethanol and acetone, and the aqueous solution is weakly acidic. Used as base fertilizer, top dressing, spraying, soaking seeds, seed dressing, rooting, etc. In addition, zinc sulfate heptahydrate is often used in the industry for beneficiation and galvanizing because the price is much lower than that of zinc sulfate monohydrate.
