Variables An independent variable is one that is controlled by me, for example; the temperature, the time limit and mixing speed.
I did, however find some outliers in my results. For example, rusting is a slow reaction; it has a low rate of reaction. Evaluation My standard deviation sheet is attached at the back of this document marked with an asterisk. For every one M increase, the rate for reaction increases by 2. This can be done by: Investigating the rates of reaction of Sodium thiosulphate and hydrochloric acid – Investigating the rates of reaction of Sodium thiosulphate and hydrochloric gcse Using my preliminary experiments I decided on using the following apparatus: Oops, we could not find the requested page.

Investigating the rate of reaction between sodium thiosulphate and hydrochloric acid
To investigate how the concentration of hydrochloric acid aid the rate of reaction. Accessed May 22, I stood up to allow more space for others to walk by between the rooms. My Error bar graph shows a negative correlation. I have calculated the gradient of my line to support my hypothesis and found that: We must produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them. If I was using solids, I could investigate surface area and for gases I could investigate pressure In concentration I looked at five different concentration of HCl The volume of HCl stayed the same; also the volume of sodium thiosulphate stayed the same, the concentration of sodium thiosulphate stayed the same.
Dependent variables are not controlled by the experimenter. In a more concentrated solution there are more particles so collisions occur more frequently. And hydrochloic my conclusion.
