Potassium hydroxide, chemical formula for KOH, also known as potassium hydroxide solution, is a strong alkaline chemicals. In daily life, it is often used as a cleaning agent, degreasing agent, acid neutralizer, electrolyte, etc. Physical Properties of

Potassium Hydroxide

potassium hydroxide is a white solid that exhibits a melting point of about 360°C at normal temperatures. At room temperature, it is soluble in water and produces a viscous, colorless liquid with a pH of 14. In life, our common detergents and soaps generally contain potassium hydroxide.

the chemical properties of potassium hydroxide

potassium hydroxide is a basic compound, acid and potassium hydroxide can be neutralized. It reacts with carbonate to dissociate and produce substances such as carbon dioxide.

the use of potassium hydroxide

1. cleaning agent: potassium hydroxide can be used as a cleaning agent or detergent, for example, can be used to clean the kitchen oil stains, accumulation of dirt and other dirt. In the laboratory, it is also used to clean experimental instruments, equipment, etc.

2. Degreasing agent: Potassium hydroxide can also be used as a degreasing agent, which can remove the fat in certain substances (such as fish, noodles, etc.).

3. Acid neutralizer: Potassium hydroxide is often used as an acid neutralizer. In some places, when the sewage is collected, potassium hydroxide is usually added to it to achieve the purpose of neutralizing the acidity of the sewage.

4. Electrolyte: In the manufacture of chemicals, potassium hydroxide is also used as an electrolyte, which can help break down certain compounds into the most basic groups for the manufacture of finished products.

safety issues of potassium hydroxide

Although potassium hydroxide is widely used in many industries, it still needs to be used with great caution. Due to its extremely corrosive nature, users should wear protective gloves, goggles, etc., and avoid deep breathing. At the same time, in the process of use, we also need to pay attention to prevent its liquid from collapsing or mixing with other substances, so as to avoid dangerous situations such as explosion.

conclusion

to sum up, potassium hydroxide as a strong alkaline chemical substances, in life and industry have a wide range of applications. It can be used to clean kitchens, remove fats, neutralize acidic sewage, make chemicals, and more. However, you must be very careful and cautious when using it to avoid safety accidents.
