Before the demonstration

Carefully clean the 1 dm flask. First use detergent and a brush, then rinse with water, followed by concentrated nitric acid and finally wash it out several times with deionised water. Thorough cleaning is vital if the demonstration is to succeed.

Make up the three solutions as follows:

Dissolve 8.5g of silver nitrate in 500 cm of deionised water. This makes a 0.1 mol dm solution.

Dissolve 11.2g of potassium hydroxide in 250 cm of deionised water. This makes a 0.8 mol dm solution.

Dissolve 2.2g of glucose in 50 cm of deionised water.
