bufor

For the flushing circulation a buffer solution is used.

Occasionally, a buffer solution is used to ensure this pH.

It can be used to make buffer solutions in the pH range 7.0-8.2.

One example of a buffer solution found in nature is blood.

It is calibrated against buffer solutions of known hydrogen ion activity.

Two or more buffer solutions are used in order to accommodate the fact that the "slope" may differ slightly from ideal.

Commercial standard buffer solutions usually come with information on the value at 25 C and a correction factor to be applied for other temperatures.

The wall's charge density is proportional to the pH of the buffer solution.

Many life forms have a relatively small pH range; an example of a buffer solution is blood.

You will need some sort of buffer solution.
