The buffer solution was a solution that could reduce the pH change with a small amount of acid or base. The pH buffer system played an important role in maintaining the normal pH value of the water and the normal environment. Most of the cells could only move within a very narrow range of pH, and a buffer system was needed to resist the pH change that occurred during the metabolism. There were three main pH buffer systems in the wine. They were egg buffer system, bickering buffer system and salt buffer system. The amount of each buffer system was different in all kinds of cells and organs.
In the research of the chemical works, the buffer solution was often used to maintain the acid-base of the experimental system. The change of the pH of the solution often directly affected the effect of studying the Pluto. If the pH value or range of the experiment system of "extracting the activity" changed, the activity of the activity would decline and even lose completely. Therefore, the preparation of the buffer solution was an indispensable and crucial step for Leena.
It was a kind of acid that was used as a buffer solution
The solution made of the weak acid and the compound acid salt could be used as a buffer. In the lab, there were three kinds of buffer systems, such as acid, lemon acid, carbon acid, vinegar, Croton acid, Tris and so on. One should carefully choose the buffer system in the experiment or study on the Pluto, because sometimes the factor that affected the test result was not the pH value of the buffer, but a kind of parting from the Pluto in the buffer. For example, the slowers such as Boris, lemon acid, Phoebe, and three kinds of chemicals, which might produce some unwanted chemical reactions.
"Boris' salt: Boris' salt is a kind of compound salt, like sugar.
Lemon salt: Lemon salt is easy to combine with calcium, so it can't affect Leena with calcium.
Phoebe: in some experiments, Phoebe was an agent or even a representative of the python, which was easy to be produced from the solution in the form of Phoebe. It was in pH7 The buffer was very effective when it was above 5 o'clock.
Three Oh, one could be used as a Pluto, but in some system, it could also be used to make a Pluto. Its main shortcoming was the effect of temperature. This was often ignored. When the pH of the Tris buffer was 7.8 at room temperature, it was 8.4 at 4 ° C, and it was 7.4 at 37 ° C. Therefore, when the buffer was tested at 37 ° C, the concentration of the hydrogen in it increased by 4 times. At pH7 Under 5, the buffer capacity was not ideal.
