Acidity $K_{a}$
Basicity $K_{b}$
The Conjugate Seesaw $K_{a}\times K_{b}=K_{w}$

### Ka assumptions

Do you always have to back up your assumption when assuming (for example) 0.1 M - X is about equal to 0.1M when the Ka is less than 10^-5 with the percent ionization?

### Re: Ka assumptions

It would be wise and in your best interest to do so.
