The pH initially increases as we add base to the solution because the base deprotonates some of the positively charged H3N+CH2CO2H ions that were present in the strongly acidic solution. The pH then levels off because we form a buffer solution

WebPolyprotic acid titration curve. We learned before that when a polyprotic acid loses its first proton, it forms a new weak acid. This is important to remember when carrying out a titration, arguably the most common and important technique in acid/base chemistry.
