Acid Base Indicator
Acid indicates the quality of all things in the world, and its color is different when it encounters acid. It can also indicate the acidity of the substance.
Acid indicates that there are often compounds in it. Or soluble in water, or soluble in alcohol, it is the same color when it encounters acid, and it is easy to change its color when it encounters it. For example, litmus, its indicator is also good. When it encounters acid, it is difficult to identify it when it encounters acid.
If it can be colored, it is because of the indicator molecule. It is also difficult to see in the context of acid. The properties of acid can improve the distribution of the sub-cloud in its molecules, causing it to absorb light differently. The human eye is different, so the color is different.
The use of acid to indicate the quality of the product. In the process of chemistry, the acid of the product, and the pH value of the liquid are all important. In the process of engineering, such as manufacturing, and metallurgy, it is also necessary to control the reaction environment and guarantee the quality of the product.
Use acid to indicate the quality, and also be careful. Different indicators have different colors. If it is not good, it is not good. And the amount used should also be controlled, too much or poor.
It is good to use it well, to be able to clarify the nature of the product, to facilitate the work, and to improve the quality of the product.
