I was going over an enolate review and it says that if there are two compounds with different acidities in the presence of a base such as hydroxide, then there will be a higher concentration of the enolate with the lower pka / higher acidity when equilibrium is reached.
Is there a way to calculate this equilibrium ratio if the pkas are known? Say one compound has a pka of 20 and the other one has a pka of 27. Is there a way to calculate the approximate ratio of the enolates that will form?
I know that for each value of pka increase, the acidity increases by exponential factors of 10^x, but I've no idea how to calculate a ratio off of this.
