Problem: Which of these combinations will result in a reaction? Check all that apply. a) K(s) + Au3+(aq) b) K+(aq) + Au(s)

FREE Expert Solution

We are asked which of these combinations will result in a reaction.


a) K(s) + Au3+(aq) 

b) K+(aq) + Au(s)


This combination would show a redox reaction. 


We need to check the reduction potential values: 

K+1(aq) + e-1 → K(s)  Ered = -2.92  V

Au+3(aq) + e-1 → Au(s)  Ered = +1.42  V
