    At 1:07:44, the question is asking about the easy of adsorption of HYDRATED alkali metal ions yes hydrated so in aqueous condition the hydration of Li+ is more so it's size will increase(I hope you all know that in aq. Condition the order of size becomes opp.) And agar size jyada hai toh adsorption jyada hoga kyoki use adsorb karne wala bhi large organic molecules hai R group. So sabse jyada Li+ than Na+ K+ Rb+ answer toh yahi mentioned hai pyqs mai!

    a) me Oxidising likh diya it supposed to be reducing agent as waha oxidation hori hai
    b) me Oxidising hoga as reduction hora hai

      See at 41:24 waha
      Oxidising agent woh hota hai jo saamne wale ko oxidise kare khud reduce ho jaye
      Jaise waha Na 0 se Na+1 gaya toh oxidise hua Na
      Aur H2O se H2 bana yaani loss of Oxygen khud reduce hua
      Toh H2O will be oxidising agent (reactant mein tha isiliye)
      Reducing agent woh hota hai jo saamne wale ko reduce kare khud oxidise ho jaye
      Toh F 0 se F -1 gaya reduce hua due to H2O
      Aur H2O se O2 bana loss of H2 which means H2O oxidise hua khud
      Hope clear hai

    Sir aapne ease of absorption wala question galat karwaya
    Ease of adsorption of the hydrated alkali metal ions on an ion-exchange resin decreases as the size of alkali metal ion increases.
    Since the order of the size of alkali metal ion follows the order-
    Li+
