Percent Ionization

[Zenita Leang 2K]

If percent ionization is more than 5% (and we were not able to approximate and determine the "x" in change in molarity as insignificant), what would we have to do to figure out K?

Then the equation for K should turn out to be a quadratic and you'd have to use the quadratic formula. The 5% approximation rule is just to make the calculations easier if the change in concentration is small enough to be negligible.

We'll have to use the quadratic formula to calculate the exact value of x.

you can use a quadratic or maybe even a cubic function if it comes down to that. Checking the percent ionization does save time though.
