What affects the speed of reaction between calcium carbonate (marble) + hydrochloric acid?
My aim is to investigate the speed of reaction between calcium carbonate (marble) and hydrochloric acid.
I think that changing the concentration of the acid will speed up the reaction rate. I think this because the higher the concentration of the acid the more particles it has to collide with.
Powering the marble chip will make the reaction go faster, I can explain this, because the marble chip is powdered the more surface area there is, which means the acid can collide more.
The temperature can also make a difference to the experiment. The greater the temperature the more particles will collide because............ I wouldn't use temperature because it is very difficult to keep the correct temperature whilst trying to perform the experiment.
The apparatus I am going to use are
. Hydrochloric Acid
2. A gas syringe to measure the volume of the gas given off.
3. Calcium carbonate (marble chips)
4. A chronicle flask to do the experiment in
5. A stop watch to record the time of the experiment
