Cl2 (g) can be generated in the laboratory by reacting potassium permanganate with an acidified solution of sodium chloride (which provides the Cl- ions ). The net ionic equation for the reaction is given above.
a. A 20.00 mL sample of 0.200 M NaCI reacts completely with excess KMnO4. The CI2 (g) produced is dried and stored in a sealed container. At 22°C the pressure of the Cl2 (g) in the container is 0.950 atm.
i.Calculate the number of moles of Cl- present before any reaction occurs.
ii. Calculate the volume, in L, of the Cl2 (g) in the sealed container.
