Marks: +1, -0
Given below are two statements :
1 M aqueous solutions of each of Cu(NO3)2, AgNO3,‌‌Hg2(NO3)2;Mg(NO3)2 are electrolysed using inert electrodes.
Given : ‌‌EAg+∕Ag∘=0.80V,‌‌EHg22+∕Hg∘=0.79V, ECu2+∕Cu∘=0.24V and EMg2+∕Mg∘=−2.37V
Statement I : With increasing voltage, the sequence of deposition of metals on the cathode will be Ag,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.
