How do you buffer a solution with a pH of 12? Socratic

WebpH of acid buffer = pKa + ( [salt]/ [acid]) The equation is the Henderson-Hasselbalch equation, popularly known as the Henderson equation. Preparation of Base Buffer Consider base buffer solution, containing a weak base (B) and its salt (BA) with strong acid. pOH, can be derived as above, pOH of a basic buffer = pKb + log ( [salt]/ [acid]) WebHowever it's unnecessary to calculate the pH of strong acid solution using the Henderson-Hasselbalch equation since we can do so using stoichiometry of H+ and assume that strong acids dissociate ~100%. So it's possible to use the Henderson-Hasselbalch equation, but it creates unneeded work when simpler methods are possible. Hope that helps.

WebExperiment 1: The pH of solution A is 7.0 i.e. it’s neutral. When we add 10 mL of 0.2M HCl to it, the pH decreases to 1.5. On the other hand, when we add 10 mL of 0.2M NaOH to solution A the pH shoots up to 12.5. In both these cases we see a drastic change in pH due to either the increase or decrease of proton [H ^\text {+} +] concentration.
