Question

The titration of a strong acid with a strong base is represented by above graph. Find the equivalence point in the titration from the above graph.

• A. A
• B. B
• C. C
• D. D
• E. E

Answer 1

Answer: (C)

C

At equivalence point the concentration of $H^{+}$ is equal to concentration of ${OH}^{-}$ so solution is neutral in case of $SA+SB$ and constant $pH$ around, so point '$C$' refer this equivalence point region after that step rise in $pH$ is due to the increase in concentration of ${OH}^{-}$ions.
