NaOH is an important chemical reagent with a variety of surprising effects and applications. It is a strong alkaline substance, also known as caustic soda, which is not only widely used in industry, but also plays an important role in daily life. The following are the amazing effects and application areas of NaOH:

1. Cleaning agent

NaOH is a good cleaning agent. It can effectively remove oil, dust and other impurities. In industrial production, NaOH is used as a chemical agent for cleaning and removing contaminants from metal and glass surfaces. At the same time, in the household cleaning, NaOH is also an effective cleaning agent, can clean the drainage pipe and kitchen utensils and other items.

2. Determine the solubility of substances

In chemical experiments, NaOH is often used to determine the solubility of different substances, such as metal salts and inorganic salts. Since NaOH is an alkaline substance, it can react with acids to produce salts and water. This reaction can help scientists determine the solubility of different substances and infer their properties.

3. depilatory

NaOH can be used as a depilatory, which can help remove fine hair and hair on the human body. NaOH alkaline can make hair shedding or off, and then achieve the effect of hair removal. However, it is necessary to carefully control the concentration and time when using it to avoid causing harm to the human body.

4. Preparation of cellulose surface

NaOH can react with cellulose to make its surface smoother and easier to squeeze and process. Therefore, it is often used in the manufacture of products made of cellulose, such as paper, fiberboard, rayon, satin, etc. NaOH can make the surface of these products harder and more durable.

5.

NaOH as a PH regulator can adjust the PH value of many substances and is used to change the acidity of the treated materials in experiments. Many substances are due to the lack of pH adjustment mechanism, resulting in unable to shape or unreliable performance. NaOH as a PH regulator can change the PH value of the material, improve its performance and durability.
