  1. Correct Answer – A
    Larger the size of the hydrated cation, smaller is the ease of adsorption. Thus ease of adsorption increase in the order : `Li^(+) lt Na^(+) lt K^(+) lt Rb^(+)`

  1. Correct Answer – b
    Ease of adsorption of the hydrated alkali metal ions on an ion exhchange resins decreases as the size of alkali metal ions increases. Since, the order of size of alkali metal ions is
    `Li^(+)ltNa^(+)ltK^(+)ltRb^(+)`
    Thus, the ease of adsorption follows the order
    `Rb^(+)ltK^(+)ltNa^(+)ltLi^(+)`

  1. Correct Answer – C
    Ease of adsorption of the hydrated alkali metal ions on an ion exchange resins decreases as the size of the alkali metal ions increases.
    Since, the order of size of alkali metal ions
    `Li^(+) lt Na^(+) lt K^(+) lt Rb^(+)`
    the ease of adsorption follows the order
    `Rb^(+) lt K^(+) lt Na ^(+) lt Li^(+)`
