WebbThe Nernst equation is E is equal to E zero minus .0592 over n, times the log of Q. Well at equilibrium, at equilibrium E is equal to zero, so we plug that in. So we have zero is equal to the standard cell potential, E zero, minus .0592 over n, times the log of Q. But at equilibrium, remember, Q is equal to K. WebbMetal ions such as Ni2+, Co2+, Cu2+, or Cr3+ are haptens with a high immunogenic potential, as contact dermatitis caused by ionic metals occurs in about 10-15% of the human population. Since alloys containing Ni2+, Co2+, and Cr3+ are components of implants in replacement surgery, dentures, orthodont …
