Approximation

What is the threshold for concentrations in which we are allowed to approximate?

If the k value is less than 10^-3 then you can approximate.

When the K value is < 10^-3, you can approximate. If you approximate, you must calculate the percent ionization in order to check. This value must be less than 5%.

The threshold is less than 10^-3 and then you would calulate percent ionization which is (H3O+ ions dissociated at equilibrium)/(initial acid) and multiply that by 100. This percent value must be under 5% to be an accurate approximation

If K < 10^-3 then you are able to approximate.

When K is smaller than 10^-3!
