Given below are two statements :
1 M aqueous solutions of each ofCu ( NO 3 ) 2 , AgNO 3 , Hg 2 ( NO 3 ) 2 ; Mg ( NO 3 ) 2 are electrolysed using inert electrodes.
Given :E Ag + ∕ Ag ∘ = 0.80 V , E Hg 2 2 + ∕ Hg ∘ = 0.79 V , E Cu 2 + ∕ Cu ∘ = 0.24 V and E Mg 2 + ∕ Mg ∘ = − 2.37 V
Statement I : With increasing voltage, the sequence of deposition of metals on the cathode will beAg , Hg and Cu .
Statement II : Magnesium will not be deposited at cathode instead oxygen gas will be evolved at the cathode.
In the light of the above statements, choose the most appropriate answer from the options given below.
