A monoprotic acid is dissolved in water to produce a 0.0136 M solution. The pH of the resulting solution is 2.45. What is the Ka of the acid?

So the question ask to calculate the Ks of the monoprotic acid where as it is dissolved in water to produce 0.0136 M solutions and the PH result of the solutions is 2.45. So the Ka of the problem is 1.25 x 10^-3. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications about the problem
