Description of Stannous sulfate

Tin(II) sulfate (SnSO4) is a chemical compound. It is a white solid that can absorb enough moisture from the air to dissolve in it, forming a solution
this property is known as deliquescence. It can be prepared by a displacement reaction between metallic tin and copper(II) sulfate:
Sn (s) + CuSO4 (aq) → Cu (s) + SnSO4 (aq)
Tin(II) sulfate is a convenient source of tin(II) ions uncontaminated by tin(IV) species.

What is Stannous sulfate?

Part I: Introduction

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 Stannous sulfate which has developed particularly rapidly in recent years. Do you know about Stannous sulfate?

The official answer: Stannous sulfate, molecular formula SnSO4, molecular weight 214.75, is a white or light yellow crystalline powder, soluble in water and dilute sulfuric acid, aqueous solution decomposes rapidly. The main use is for tin plating or chemical reagents, such as alloy, tinplate, cylinder piston, steel wire, and another acid plating, bright tin plating of electronic devices, etc. In addition, also used for aluminum alloy products coating oxidation coloring, printing, and dyeing industry as a mordant, organic solution of hydrogen peroxide remover, etc.

What’s the application of Stannous sulfate?

Stannous sulfate can be produced by reacting metallic tin with dilute sulfuric acid.
Add 120 g of tin grains to 130 mL of 9 mol/L sulfuric acids and boil for several hours until the tin is no longer dissolved. The solution was poured out and heated with about 250 ml of water to extract the remaining SnSO4. The two solutions were combined and filtered. The solution was evaporated under a vacuum until a paste was formed and then cooled, and the resulting salt was separated using a Brønsted funnel and washed twice with ethanol, and then dried.
It is mainly used for tin plating in the electroplating industry, oxidation coloring of aluminum alloy surface, mordant in the printing and dyeing industry, hydrogen peroxide remover, etc.

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.
