Geo-Scientist Prelims 2022 Chemistry Q78: Which of the following statements regarding conductometric…

Which of the following statements regarding conductometric titrations involving acids and bases is/are not correct? [In each case, the base (alkali) is added to the acid contained in the conductivity cell as the titration progresses]

1. The electrical conductance depends only on the mobility, but not on the number of ions.
2. The titration of a strong acid against a strong base yields a V-shaped plot.
3. Titrations of a strong acid against a weak base and a weak acid against a strong base yield identical-shaped plots.
4. In a titration involving a mixture of a strong acid and a weak acid against a strong base, the strong acid is neutralized first.

Select the correct answer using the code given below.

1. (a) 1 and 4
2. (b) 1 only
3. (c) 2
4. (d) 1 and 3
