Solution: Consider the following voltaic cell. What is the change in the cell voltage when the ion concentrations in the anode half-cell are increased by a factor of 10?

Problem

Consider the following voltaic cell.
A diagram shows a simple voltaic cell, with iron and silver electrodes. Two beakers are connected by a salt bridge.  The beaker on the left contains a one molar Fe2+ (aqueous) solution and has an Fe (solid) electrode; the beaker on the right contains a one molar Ag+ (aqueous) solution and has an Ag (solid) electrode.  A voltmeter is connected to both electrodes; electron flow through the voltmeter is from the Fe electrode toward the Ag electrode.
