Use the cell notation to answer the question:
Cr(s) | Cr3+(aq) || Br–(aq) | Br2(g) | Pt(s)
What is the reducing agent?
Group of answer choices
Br2(g)
Cr3+(aq)
Pt(s)
Cr(s)
Br–(aq)
Cr(s)Cr3+ + 3e-
Br- (aq)1/2 Br2 (g) + 1e-
in the given cell representation cr acts as anode br- acts as cathode
so oxidation of cr will take place and will acts as reducing agent
cr(s) acts as reducing agent
here pt acts as inert supporting electrode
hope it will help you
thank you
have a nice day :)
