When an ion-selective electrode for sulfate was immersed in 0.0300 M sodium sulfate, the measured potential was 0.0460 V. What is the concentration of sulfate when the potential is 0.0610 V? Assume that the electrode follows the Nernst equation, the temperature is at 25°C, and that the activity coefficient of sulfate is 1.
I have done this a couple different ways and it keeps saying it's incorrect.
First I got 0.0539M and the second time I got 0.0167M. Both of which are wrong.
