The table below shows two half-cells, A and B, used to assemble an electrochemical
cell under STANDARD CONDITIONS.
8.1 State the energy conversion that takes place in this cell. (1)
8.2 Calculate the mass of silver nitrate, AgNO3, used to prepare 150 cm3 of the electrolyte solution in half-cell B. (4)
8.3 Define the term reducing agent. (2)
8.4 Write down the:
8.4.1 NAME or FORMULA of the reducing agent (1)
8.4.2 Balanced equation for the reaction that takes place (3)
8.5 Calculate the initial emf of this cell. (4)
8.6 How will the emf of the cell be affected if the concentration of the copper ions in half-cell A increases?
Choose from INCREASES, DECREASES or REMAINS THE SAME. (1)
