If Ka1 and Ka2 are sufficiently distinct and a polyprotic acid is titrated with a strong base, the pH curve will contain two equivalence points because the two acidic protons will be titrated sequentially.
<h3>What is titration?</h3>
Titration is a method of chemical analysis in which the amount of a sample's constituents is determined by adding a precise amount of a different substance—one that the desired constituent reacts with in a specific, known proportion—to the sample being tested.
The titrating reagent, or titrant, is gradually added to the process using a standard solution (i.e., a solution of known concentration), which is administered using a burette, which is essentially a long, graduated measurement tube with a stopcock and a delivery tube at its bottom end. The addition comes to an end at the comparable point.
