WebEthanoic acid is a typical weak acid. It reacts with water to produce hydroxonium ions and ethanoate ions, but the back reaction is more successful than the forward one. The ions react very easily to reform the acid and the water. At any one time, only about 1% of the ethanoic acid molecules have converted into ions.

WebWeak acid v weak base The curve is for a case where the acid and base are both equally weak - for example, ethanoic acid and ammonia solution. In other cases, the equivalence point will be at some other pH. You can see that neither indicator is any use. WebStrong acids will tend to have a high Ka and low pKa value while weak acids have small Ka and high pKa values. Weak Bases The concept is very similar when thinking about a weak base; however, in this case, a weak base is a base that cannot fully ionize or fully accept hydrogen ions in a solution.
