CHXI10:THE S-BLOCK ELEMENTS

315806 The reducing power of a metal depends on various factors. Suggest the factor which makes \(\mathrm{Li}\), the strongest reducing agent in aqueous solution.

1 Sublimation enthalpy
2 Ionisation enthalpy
3 Hydration enthalpy
4 Electron-gain enthalpy
CHXI10:THE S-BLOCK ELEMENTS

315807 Alkali metals displace hydrogen from water forming bases due to the reason that

1 They are far above the hydrogen in electrochemical series based on oxidation potential.
2 They are far below the hydrogen in electrochemical series based on oxidation potential.
3 Their ionization enthalpy is less than that of other elements.
4 They contain only one electron in their outermost shell.
CHXI10:THE S-BLOCK ELEMENTS

315808 Alkali metals have negative reduction potential and hence they behave as

1 oxidising agents
2 Lewis bases
3 reducing agents
4 electrolytes

CHXI10:THE S-BLOCK ELEMENTS

315804 Statement A :
Alkali metals are obtained by electrolysis of molten salt and not aqueous solution.
Statement B :
The discharge potential of \(\mathrm{H}^{+}\)ions is lower than alkali metal cation hence hydrogen is discharged at cathode instead of metal.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
