How do you work out ka from pka

Web29 mrt. 2024 · If the value of Ka for acid is known, we can easily find its pKa value by taking the negative logarithm of Ka. The formula to determine pKa from Ka is [pKa = -log10Ka]. … WebFor methyl red, the pKa value is approximately five. And the goal is to match the pKa value as closely as possible to the pH at the equivalence point. But since the pH at the equivalence point is between eight and 10, that's too far away from five. So by looking at the pKa value, we know that methyl red is not a good fit for this titration.
