An investigation to find out how the concentration of acid affects the rate of reaction between hydrochloric acid (HCl) and limestone (CaCo3)
Aim
My aim for this experiment is to find out if the concentration, which is the variable I am changing, affects the rate of reaction between CaCO3 & HCl.
Prediction
My prediction is that if the concentration of the acid increases there will be an increase in the rate of reaction for example the highest concentration will have the fastest reaction time.
I used a preliminary test to help in the prediction. I went and prepared marble chips and concentrated acid, we tried the experiment, the results was clear that as in a few seconds it was almost finished. When we used very dilute acid it took so long for it to react and the amount of bubbles were much less than the first one.
By using the results I can make the prediction of that, the rate of reaction is affected by concentration.
Hypothesis
If the concentration of an acid increases then the rate of reaction will also increase. When the acid has a high concentration that means in that solution, compared to a dilute one there are more particles available to react with therefore the amount of times they will collide with each other is more. I got this information from GCSE chemistry book and my own knowledge
Introduction
There are many different factors, which affect the rate of reaction. Below are most of the known factors, which affect the rate of a reaction:
. The size of the particles of a solid reactant.
2. The concentration of the reactants solution.
