Question

a mixture contains iron(iii)chloride, zinc(ii)oxide and potassium chloride . describe how each of the substance can be obtained from the mixture

Answer 1

Explanation:

Add ethanol to the flask containing the mixture of iron(III)chloride,zinc(II)oxide and potassium chloride.Iron(III)chloride being highy soluble in ethanol,it disolves leaving the insoluble Potasium chloride and zinc(II)oxide as solid.Filter the mixture to obtain iron(III)chloride as filtrate and a mixture of

Potasium chloride and zinc(II)oxide as residue.Warm the solution of iron(III)chloride to evaporate the ethanol that highly siblimes leaving iron (iii) chlodide as crystals.Transfer the residue in another flask and add water to it.Potassium chloride being highly soluble in water,it dissolves leaving the insoluble Zinc
