Buffer Calculator

Buffer
pKa:Mw(g/mol):
pH
Concentration (M)
Volume (l)
Concentration HCl/NaOH (M)

Recipe:

The amount of titrating agent is calculated using the formula:

pH = pKa + lg([bufferdeprotonated]/[bufferprotonated])

5 M HCl can be made up as follows:
dissolve 491 ml HCl 32 % or 417.5 ml HCl 37% in water up to a final volume of 1 l
