When some areas enter the plum rain season, the air will become extremely humid, which will have a bad impact on food storage and people's normal life. In order to avoid the heavy losses caused by the weather in this period, many dehumidification products are widely used.
Chemical products are often used in life and industry production, and also play different roles. When it is used as a chemical reagent, it can react with many other chemical reagents. So, can it react with hydrogen peroxide? The specific analysis is as follows.
Potassium hydroxide is a kind of chemical raw material, but there may be a big gap in the quality of potassium hydroxide produced by manufacturers. Why is there such a big gap? Let's get to know today.
Both boys and girls use facial cleanser in the morning and evening every day, because the face will be polluted by various kinds of radiation and dust in the daytime.
Potassium hydroxide is also known as caustic potash and caustic soda. Its chemical formula is KOH. The pure product is white rhombic crystal. The industrial product is white powder or flake solid.
1. Used as desiccant, absorbent, oxalic acid and various potassium salts, plating, sculpture, lithography, etc. 2. Mainly used as raw materials for potassium salt production, such as potassium permanganate, potassium carbonate, etc.
1. Transportation matters needing attention: Open truck transportation with steel drum packing is available for railway transportation. The packing should be complete, and the loading should be safe at the time of shipment.
Potassium hydroxide (chemical formula: KOH, formula: 56.1) white powder or flaky solid. Melting point 380 C, boiling point 1324 C, relative density 2.04g/cm3, refractive index n20/D1.421, vapor pressure 1 mmHg (719 C).
Chemical formula of potassium hydroxide: Koh, its solid appearance is white powder or flake, with strong alkalinity and corrosiveness, easy to dissolve in water, easy to absorb moisture in the air to deliquesce or absorb carbon dioxide to generate potassium carbonate, so it can be used as desiccant.
We have heard that potassium hydroxide will appear some black when it is being produced. That's because some of the substances are affected by the production, or there are some problems in the process. But sometimes it will appear red when it is being produced. Why.
