Problem- When an ion-selective electrode for X was immersed in 0.0510 M XCl, the measured potential was 0.0340 V. What is the concentration of X when the potential is 0.0490 V? Assume that the electrode follows the Nernst equation, the temperature is at 25°C, and that the activity coefficient of X is 1.
