Describe how you would prepare iron (II) sulphate from iron metal dust and a suitable dilute acid. Include an equation for the reaction.
Answers to Questions 4.4.1(c)
Warm about 50 ml of dilute sulphuric in a glass beaker.
Add iron dust in small quantities, stirring with a glass rod till a small excess of the iron dust remains unreacted.
Equation: Fe(s) + H2SO4(aq) ⟶ FeSO4(aq) + H2(g)
Filter off the excess iron dust.
Heat the solution to saturate it. Then allow it to cool and crystallize.
Filter off the mother liquor and mop the crystals dry.
