Assertion `(A):` The mobility of `Na^(o+)` is lower than that of `K^(o+)` ion. Reason `(R): ` The ionic mobility depends upon the effective radius of the ion.A. If both `(A)` and `(R)` are correct, and `(R)` is the correct explanation of `(A)`.B. If both `(A)` and `(R)` are correct, but `(R)` is not the correct explanation of `(A)`.C. If `(A)` is correct, but `(R)` is incorrect.D. If `(A)` is incorrect, `(R)` is correct. |

Answer» Correct Answer - C `(A)` is correct but `(R)` is incorrect. In aqueous medium, the mobilities of cations depend on`:` `(i)` Charge density `[(` ionic charge `//` ionic size `)` ratio`]` ` (ii)` Extent of hydration Decreasing order of mobility of cations of first groups are `:` `Cs^(o+)gt Rb^(o+), K^(o+)gtNa^(o+)gtLi^(o+)` |
