2. Could you experimentally determine if the water is safe to drink by setting up a different electrochemical cell? This involves using a Pb wire and a suitable reference electrode and measuring the equilibrium potential of the Pb wire and the dissolved Pb2+ cations in the water sample? write a few sentences fully explaining your thoughts.

![B.
Since 1993 the World Health Organization (WHO) has maintained that the
smallest maximum allowable level of lead in drinking water is 5µg/L. A colleague of yours
is collecting samples from the drinking water supply in a foreign country and is using an
electrochemical technique to determine the amount of Pb²+ cations in the water. He set
up an electrochemical cell of 1 L (liter) in volume and used the water sample containing
Pb²+ cations to electroplate Pb on to an inert gold cathode. The electroplating was
completed in 1 week. Then he stripped the metallic Pb from the gold surface and
measured a charge under the stripping curve of 3.71 x 10-³ coulombs.
1. According to the WHO, is the water safe to drink? Show all work.
