Which acid or base (along with its corresponding salt) should be used to generate a buffer solution with ph around 3. 5?

Sagot :

Formic acid, Sodium formiate will generate a buffer solution with pH around 3. 5.

It must consider the acid whose pKa = pH in order to choose the base or acid that can produce a buffer solution with such a pH of about 3.5.

However, it also need to consider buffer capacity, which is a factor that can alter the pH of a solution by one unit in a liter.

The connection between the components' concentrations and their concentrations themselves affects buffer capacity in addition to their individual concentrations.

Therefore, Formic acid, Sodium formiate will generate a buffer solution with pH around 3. 5.
