This salt exists as a series of compounds that differ in their degree of hydration. The anhydrous form is a pale green or gray-white powder, whereas the pentahydrate (CuSO4·5H2O), the most commonly encountered salt, is bright blue.

Other names for copper(II) sulfate are “blue vitriol” and “bluestone”.

What is Copper(II) sulfate?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Copper(II) sulfate which has developed particularly rapidly in recent years. Do you know about Copper(II) sulfate?


The official answer: Copper(II) sulfate is an inorganic compound with the chemical formula CuSO₄, anhydrous Copper(II) sulfate is for a white or off-white powder. Copper(II) sulfate is both a fertilizer and a commonly used fungicide. Bordeaux solution, copper soap solution, and copper ammonium preparations are made from Copper(II) sulfate with quicklime, soap, and ammonium bicarbonate.

What’s the application of Copper(II) sulfate?

Copper(II) sulfate can be used to kill fungi. It is mixed with lime water to produce a Bordeaux solution, which is used to control fungi on crops such as lemons and grapes. Dilute solutions are used for sterilization in aquariums and for removing snails. Since copper ions are toxic to fish, the amount must be strictly controlled. Most fungi require only very low concentrations of Copper(II) sulfate to be killed. In addition, Copper(II) sulfate can also be used to control E. coli. The aqueous solution of ketone sulfate has a strong fungicidal effect and is mainly used in agriculture to control many diseases of fruit trees, malt, potatoes, and rice with good effect, but it has a poor effect on rust and powdery mildew. At the same time, the plant produces drug damage, while only on the copper ion drug tolerance of crops or dormant fruit trees used. It is a preventive fungicide and needs to be used before the onset of disease. It can also be used to remove algae from rice fields and ponds. It is also a trace element fertilizer, which can improve the stability of chlorophyll, prevent chlorophyll from being destroyed prematurely, promote crop absorption, crop loss of green when copper is deficient, and fruit trees when copper is deficient, the fruit is small, the flesh becomes hard, and in serious cases, the fruit trees die. crops sensitive to copper are cereal crops such as wheat, barley, oats, etc. It is mainly used for seed treatment and extra-root fertilization.

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
