Question

The electrolysis cell shown here was run at a constant current of 0.021 96 A. On one side, 49.22 mL of H2 were produced (at 303 K and 0.996 bar); on the other side, Cu metal was oxidized to Cu21. (a) How many moles of H2 were produced? (See Problem 16-16 for the ideal gas law.) (b) If 47.36 mL of EDTA were required to titrate the Cu21 produced by the electrolysis, what was the molarity of the EDTA? (c) For how many hours was the electrolysis run?

Definition Definition Any of various laws that describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. At a constant temperature, the pressure of a particular amount of gas is inversely proportional with its volume (Boyle's Law) In a closed system with constant pressure, the volume of an ideal gas is in direct relation with its temperature (Charles's Law) At a constant volume, the pressure of a gas is in direct relation to its temperature (Gay-Lussac's Law) If the volume of all gases are equal and under the a similar temperature and pressure, then they contain an equal number of molecules (Avogadro's Law) The state of a particular amount of gas can be determined by its pressure, volume and temperature (Ideal Gas law)
