Chemistry
CHEMISTRY INVESTIGATION In our investigation, we are trying to speed up a reaction. For our investigation we will use hydrochloric acid and thiosulphate to make sodium chloride + water + sulphur + SO2. VARIABLES The variables that could be involved are, increase in concentration increase temperature increase surface area adding a catalyst Out the variables that I have, the one I will change is the concentration, I will increase it. This will be my input variable, because it is the most accurate and also easy to change out of the possible variables.
