A student measures Ecell of a concentration cell created by having the saturated solution of AgBr on one side and 0.10 M Ag*(aq) on the other (along with silver electrodes). The experimental value is 0.627 V. The student is told to use the theoretical value of the Nernst plot (-0.0591 V). (The concentration of the halide is also 0.10 M.) (a) In which direction will electrons spontaneously flow? O from the 'saturated side' to the '0.10 M side' from the '0.10 M side' to the 'saturated side' the electrons will not flow in this cell (b) What is the value of [Ag+]dilute? M (c) What the experimental Ksp?
