What reactions happen at the cathode and anode?

the electrode potantail of pd is 0.987

the reduction potentail of Ni is -0.25

for pd is +0.987

Answer 1

toon # Reduchion. Pd²+ + H₂ - Pdlo) + 246 feasible L oxidatimi lor spontangan occurs at occurs at: Oxidation - anode to Reduction = Cathode In order to determine if the reaction is feasible on nut we check 4G. f 4G = -ve (feasible) I J 4G = (tred non feasible AG = Stred Now 4G = -nf E cell 2 H E cell = the (feasible) Eelle E Cathode - E anode A Fall-C-vel non det pd2t Pacol E= 0.95Lv. 20-t. 1 aut H₂ in E = 0.ov. Since Pd is Cathode in his anode Belle Ecotech - Eanade - 0.951V- 0'OV:- 0.951V Since Full = tre = G = -ve Hence this reaction is feasible. #dé+ Pd2+ - Pdco) + de H₂ ant t de oxidation at anode) T Reduction at Cathode) /

Pd is oxidizing agent and the is reducing agent. oxidation # Ni2+ + h - N; Co) + 240 Reduction Anode: Cathode: H₂ + 2H+ + de Ni2+ + aé Nico) Coxidation) C Reduction) # Oxidation always occuro at anode. Ni2+ is coxidizing the hence it is oxidizing agent this reducing Nit hence it is Reducing agent & Ni 2+ + 20 24 + + 2e - Nico) H2 E = – 0.257.
