The sensitivity of a coulometer is governed by the delivery of its minimum current for its minimum
Question:
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 by 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?
