Factors Affecting the Rate of Reaction Between Sodium Thiosulfate and

Factors Affecting the Rate of Reaction Between Sodium Thiosulfate and

Hydrochloric acid.

Plan

I will be conducting an experiment to find out if concentrating

Thiosulfate and Hydrochloric Acid will effect the rate of reaction.

I predict that the higher the concentration of the Thiosulfate, the

quicker it will react with the Hydrochloric Acid.

I will test:

20 Acid

20 Thio

0 Water

20 Acid

15 Thio

5 Water

20 Acid

10 Thio

10 Water

15 Acid

20 Thio

5 Water

10 Acid

20 Thio

10 Water

The total volume of all the liquids will be kept the same. As will the

temperature, conical glass, measuring cylinder and the cross on the

piece of paper. I will ensure that all these are kept the same by

doing all the experiments on the same day, not changing my equipment

and the to...
