Question

Describe in detail with the help of diagrams the preparation of a pure, dry sample of zinc sulfate

crystals. (include a chemical equation for the reaction​

Answer 1

your answer is below ____________

Step Explanation

Heat acid (H2SO4) in a beaker Speeds up the rate of reaction

Add base (CuO) until in excess (no more copper oxide dissolves) and stir with glass rod Neutralises all the acid

Filter the mixture using filter paper and funnel Removes any excess copper oxide

Gently heat the filtered solution (CuSO4) To evaporate some of the water

until crystals form on a glass rod Shows a hot saturated solution formed

Allow the solution to cool so that hydrated crystals form Copper sulfate less soluble in cold solution

Remove the crystals by filtration Removes crystals

Dry by leaving in a warm place Evaporates the water
