Apparatus;

Measuring cylinder, measures the solution

Conical Flask, holds the solution

Heat Proof mat, protects the surface

Tripod, holds gauze and flask enabling the flame to reach it

Gauze, a mat to flask on

Bunsen Burner, heats the solution

Tongs, picks up flask safely

Paper with cross on it, to see when solution goes cloudy

Thermometer, measures the temperature of the solution

Safety Goggles, protects your eyes

Plan;

I think that the results of the experiment will change according to the temperature of the Thiosulphate. I predict that the hotter the temperature, the faster the Thiosulphate will become cloudy. For example, at room temperature, which is about 25'c, I predict that the Thiosulphate will take at least two minutes to become cloudy, however, as the heat increases, to about 55'c, the Thiosulphate will take only...
