The physical and chemical properties of potassium hydroxide:

The appearance of potassium hydroxide is white lumps or powder, with strong corrosiveness and strong alkalinity. When potassium hydroxide is exposed to gas, it is easily wetted by moisture in the air, digesting and absorbing carbon dioxide to become potassium carbonate.

The chemical equation of potassium hydroxide is KOH, the relative molecular mass is 56.1, the melting point is 1324°C, the melting point is 360.4°C, and the density (water = 1) is 2.04. Potassium hydroxide generates a lot of heat when it is dissolved in water, alcohol or acid. The pH of the 0.1 mol/L aqueous solution is 13.5.

Potassium hydroxide has basic properties:

Potassium hydroxide reacts with partial alkali to make the stamen test solution appear blue, and the phenolic o-benzene test solution appears red.

Potassium hydroxide has a cauterizing effect on tissues, can dissolve proteins, and produce alkaline-transforming proteins. Water solution and dust splash on the skin, especially on the mucous membrane, causing scars. The higher the concentration of the substance and the higher the temperature, the stronger the effect. Splashing in the eyes will not only damage the cornea, but also continue to damage the deep tissues of the eyes.

When potassium hydroxide is transported and stored in logistics, it should be prevented from being transported with flammable materials or mixed mixtures of combustibles, acids, edible chemicals, etc. The packaging is intact and transported securely. Prevent sending leakage during logistics transportation.
