Question
English (Saudi Arabia) measured a charge under the stripping curve of 3.71 x 103 coulombs. 1. According to the WHO, is the water safe to drink? Show all work. Page 4 of 4 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.

Show all work and the equations used to construct the diagram. F5 -57,000 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 103 coulombs.
