How to prepare 0.2M Hydrochloric acid, and 1.2 PH-Hydrochloric acid buffer solution?
Hi there,
You can't generate a buffer solution using a strong acid alone. If you want to generate a HCl solution at pH 1.2, HCl will 10-1.2M = 6.31*10-2M.As for the 0.2M HCl solution, all you have to know is that concentrated HCl is 12M. So these are simple dilution issues.

When diluting concentrated HCl, make sure you add the acid into the larger volume of water. Do not add water into the concentrated acid. It's a safety issue.
