Re: Ka value
Really strong acids that dissociate completely do not have a Ka value. However we classify really weak acids with a Ka value of less than 10^(-3)

Re: Ka value
Since strong acids fully disassociate, just know that they won't even have a Ka value because there's no reactants at the end of the reaction. If Ka=[P]/[R] and there's no R, then you won't have to worry about Ka for strong acids, only weak acids.

Re: Ka value
You should only be worried about what Ka value is associated with a weak acid, since this will determine whether or not you can make assumptions. However for the midterm, Dr. Lavelle said there would be no questions in which you can make the assumption that x is essentially insignificant.
