Question

Based on the experimental data, I was able to calculate the experimental pKa value which is 5.04 and the literature value of the pKa for KHP is 5.51. If I would be computing for the relative error between the two pKa's it would be 8.52994555%. But then, what i need is the relative error between the experimental and theoretical Ka. So, I calculated for the Ka of both and got the following: experimental Ka is 9.12010839E-6 and the theoretical Ka is 3.0902953E-6. And based on this I calculated for the relative error of the two Ka's and I got a relative error of 195.120923%
