### Number of significant figures when using Ka and Kb

Question: When doing calculations involving the $K_{a}$ value or the $K_{b}$ value, do we consider that value (along with the others given) for the number of significant figures in the final answer? Or are $K_{a}$ and $K_{b}$ considered constants?

I think you should depend your SF on other numbers, instead of Ka and Kb. Ka and Kb will change due to several factors.
