The sensitivity of a coulometer is governed by the delivery of its minimum current for its minimum time. Suppose that 5 mA can be delivered for 0.1 s.(a) How many moles of electrons are delivered at 5 mA for 0.1 s? (b) How many milliliters of a 0.01 M solution of a two-electron reducing agent are required to deliver the same number of electrons?
