The reaction gcse sodium reaction and HCL Length:. There is five factors which affect the rate of a reaction, according to the collision theory of reacting particles: The independent variables in our experiment are the concentration of hydrochloric acid. These are circled on my graphs. Papers] Gcse Essays words 3. This ensures that the solution is completely opaque when I stop the timer. I predict that as the concentration of the Sodium Thiosulphate doubles, the rate of the reaction will double.

I stood up to allow more space for others to walk by between the rooms. As soon as the chemicals were in, I started the timer. In my investigation, there was the limitation of room temperature. The reaction will sodium and eventually the solutionwill turn completely opaque Free Essays words 5. Research Papers words 4.
