NEETChemistryIonic Equilibrium
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?
Options
- AA
- BB
- CD
- DC
Correct answer
A. A
Step-by-step solution
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. H C l S A + N a O H S B → N aCl + H 2 O l at equivalent point p H = 7 and at endpoint solution will be neutral.
