Topic: The Rate of Reaction Between Sodium Thiosulphate and
Hydrochloric Acid
Research Question : what is the rate of reaction between Sodium
Thiosulphate and Hydrochloric Acid in different concentaration
Aim : to investigate the effect of changing the concentration of
Sodium Thiosulphate on the rate of reaction between Sodium
Thiosulphate and Hydrochloric acid.
Hypothesis : As the concentration of Sodium Thiosulphate
increases , so do the length of time for cross behind the glass to
disappear decreases. This is because the increase of concentration
of Sodium Thiosulphate will increase the rate of reaction between
Hydrochloric acid and sodium Thiosulphate particles.
