Approximation

How do we check if our approximation is correct when finding ph?

In general, I think you can find the percent pronation, and if this value is less than 5%, then your approximation was valid.

You can check the percent protonation to see if it's less than 5%. You can also check the Ka/Kb value. if the value is less than 10^-3, you can almost safely approximate.
