Which of the following is/are correct
statement(s) for the addition of Li, K, Rb to
the aqueous solution of Na+
--
(i) The correct order of metals in which they
reduce the Na+
ion is Rb <K < Li.
(i) Reduction of metal ions would not take
place.
(a) Statement (i) and (ii) are correct.
(b) Statement (i) is correct only.
(c) Statement (ii) is correct only.
(d) Neither (i) nor (ii) is correct
Answers
Answer: solve it as this
Explanation:
Answer:
Neither (i) nor (ii) is correct
Explanation:
(a) As alkali metals progress down the group, their atomic and ionic sizes grow larger. As the size expands, the amount of hydration decreases.
The degree of hydration and ionic mobility are inversely proportional.
As a result, the increasing order of alkali metal ionic mobilities is observed Li⁺<Na⁺<K⁺<Rb⁺<Cs⁺.
(b) Nitride ion is best compatible with small Li ions. As a result, a considerable quantity of lattice energy is released during the production of lithium nitride. This energy is sufficient to overcome the high energy necessary for nitride ion production.
(c) The electrode potential value is determined by the following factors.
(i) Enthalpy of ionizing (ii) Enthalpy of hydration
(iii) Vaporization enthalpy.
The net effect of the following components is the same for Ba, Sr, and Ca. As a result, the possibilities of their electrodes are practically constant.
