Thanks for the reply. I was thinking in the same direction, in terms of using the same acid or base the buffer was made from. Thanks again

Hi All, I have a question about adjusting the pH of a buffer solution. I believe it is not correct to adjust the pH of any buffer by simply adding a few drops of HCl or NaOH, this would introduce a new ion into the solution if Na or Cl was not present in the original solution. Is this a correct philosophy or am I just being stupid? Thanks all
