Instructions

The concentration of potassiumions inside a biological cell is at least twenty times higher than the outside. The resulting potential difference across the cell is important in several processes such as transmission of nerve impulses and maintaining the ion balance. A simple model for such a concentration cell involving a metal M is:
$$M(s)\mid M^{+}(aq; 0.05 molar)\mid \mid M^{+}(aq; 1 molar)\mid M(s)$$
For the above electrolytic cell the magnitude of the cell potential $$\mid E_{cell}\mid=70 mV$$.

Question 18

If the 0.05 molar solution of $$M^{+}$$ is replaced by a 0.0025 molar $$M^{+}$$ solution, then the magnitude of the cell potential would be
