QUESTION 8 Given below are the half equations and standard reduction potential values for Ni²+ and Cr³+ ions. Ni²+ (aq) + 2e → Ni (s) Cr³+ (aq) + 3e → Cr (s) Ered = -0.23 V Ered = -0.73 V Calculate the cell potential for a cell containing 3.0 x 104 M Ni²+ ions and 4.0 x 10³ M Cr³+ ions. (Answer: El=0:449-V) (5 marks)
