What would be the resulting pH if you mix equal amounts of an acid and a base that are the same numerical distance from neutrality (e.g., pH 5 + pH 9)?
Homework Answers
The solution with pH=5 is a weak acid solution whose concentration is=1 x 10^-5N
The solution with pH=9 is a weak base solution whose concentration is=1 x 10–5N, (because it's pOH is 14–9=5).
So an acid and a base (both weak) of equal volume and equal concentration are mixed together we will get a neutral solution.
It's pH will be 7
