Example 12.7

Postby Erin Jannusch » Fri Dec 08, 2017 4:52 pm

In example 12.7 of the text, why is the "-x" eliminated from the denominator of the expression for Ka? Does this portion of the equation not affect the result?

The "-x" is eliminated because the Ka is so small that the change in initial concentration is insignificant.
