Question

For the given cell notation, write an overall cell reaction:Ni(s) | $$Ni^{2+}(aq$$) || Br_{2}(l) | $$Br^{−}(aq$$) | Pt(s)Explain why we need an inert electrode at the cathode.

Accepted Answer

Ni(s) + Br_{2}(l) → $$Ni^{2+}(aq) + 2$$ $$Br^{−}(aq) An $$inert electrode is needed so that it does not react with bromine.

Answer

Ni(s) + Br_{2}(l) → $$Ni^{2+}(aq$$) + $$Br^{−}(aq) An $$inert electrode is needed so that it adsorbs the liberated bromine.

Answer

$$Ni^{2+}(aq) + 2$$ $$Br^{−}(aq$$) → Ni(s) + Br_{2}(l) An inert electrode is needed to adsorb hydrogen gas.

Answer

$$Ni^{2+}(aq$$) + $$Br^{−}(aq$$) → Ni(s) + Br_{2}(l) There is no need for an inert electrode.

For the given cell notation, write an overall cell reaction:Ni(s) | Ni2+(aq) || Br2(l) | Br−(aq) | Pt(s)Explain why we need an inert electrode at the cathode.

For the given cell notation, write an overall cell reaction:
Ni(s) | Ni²⁺(aq) || Br₂(l) | Br⁻(aq) | Pt(s)Explain why we need an inert electrode at the cathode.
