Molten potassium bromide can be electrolysed. Predict the name of the product formed at the:
a) anode
d) cathode.
Give the symbols of the ions present in water.
In the electrolysis of copper chloride solution, copper is formed at the cathode and chlorine at the anode.
a) Explain how the copper ions (Cu 2+ ) change into copper atoms (Cu).
b) Explain how the chloride ions (Cl − ) change into chlorine molecules (Cl 2 ).
c) Write a balanced equation, with state symbols, for the overall decomposition of copper chloride.
15 In the electrolysis of sodium chloride solution, hydrogen is produced at the cathode and chlorine at the
anode.
a) Explain why sodium is not produced at the cathode.
b) Give the name of the solution left at the end of the electrolysis.
16 In the electrolysis of sodium sulfate solution, hydrogen is produced at the cathode and oxygen is produced
at the anode.
a) Predict the products formed during the electrolysis of potassium chloride solution.
b) Predict the name of the solution left at the end of the electrolysis of potassium chloride solution.

In november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
