Given below are two statements:
| Assertion (A): | Conductivity of all electrolytes decreases on dilution. |
| Reason (R): | On dilution number of ions per unit volume decreases. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
The incorrect statement(s) among the below is/are:
| (a) | The unit of conductivity is S cm–2 |
| (b) | Specific Conductivity of weak and strong electrolytes always decreases with a decrease in concentration. |
| (c) | The unit of molar conductivity is S cm2 mol–1 |
| (d) | Molar conductivity increases with an increase in concentration. |
1. Only (a)
2. (a) and (d)
3. (b) and (d)
4. (a) and (c)
Consider the following graph.
The strong electrolyte in the above graph is represented by:
1. X
2. Y
3. Both X and Y
4. Data given is not sufficient to predict.
| Assertion (A): | The conductivity of a solution decreases with dilution. |
| Reason (R): | Conductivity of a solution depends on the number of ions and the number of ions decreases when the solution is diluted. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
