Question

In an acid-base titration, 0.1 M H C l solution was added to the N a O H solution of unknown strength. Which of the following correctly shown the change of p H of the titration mixture in this experiment?

TestHub · Accepted Answer

For titration of strong base with strong acid $p H$ changes sharply near equivalence point and at equivalent point $p H$ sharply decreases because strong base & strong acid dissociate completely.
$\overset{S A}{H C l} + \overset{S B}{N a O H} \to N aCl + H_{2} O (l)$
at equivalent point $p H = 7$ and at endpoint solution will be neutral.
