Hey guys I need help.

Suppose I have a 5ml 0.25M solution of CH3COOH. I manually measured the pH with an electric pH meter and got pH 2.80.

I then diluted the solution to 50.0ml for a molarity of 2.5x10^-4M. The measured pH of this solution was 3.23.

How do I find the "theoretical pH" of these two solutions? I have no clue.

The Ka of CH3COOH is 1.8x10^-5

Thanks
