3.2 Can you store copper sulphate solutions in a zinc pot?
3.8 Consult the table of standard electrode potentials and suggest three
substances that can oxidise ferrous ions under suitable conditions
​

Answer 1

Answer:

3.2 Copper is less reactive than zinc. Zinc will replace the copper from its salt solution. ... So copper sulphate solution cannot be stored in a zinc pot.

3.8 Three substances that can oxidize ferrous ions are bromine, chlorine and silver. These elements lie below the iron in the electrochemical series. Note: The metals that have higher reduction potential than iron, will oxidize iron. These metals are silver, bromine and chlorine.
