How does concentration change the rate of reaction of limestone and Hydrochloric social disease?

The four things capable of changing the rate of reaction are, the move up area, the concentration, changing the temperature or adding a catalyst.



In this experiment I will change the concentration of the bitter as it is lite to control and easy to verse. I chose not to change the come in area due to the fact that it is actually difficult to measure exactly the surface areas as a lovely normalization is needed to measure this. This sort of equipment which has such a fine calibration is very difficult to get hold of and is very expensive.

The reaction which will happen:

Calcium carbonate + Hydrochloric acid Calcium chloride + Carbon dioxide + water

Ca CO? (s) + 2HCl (aq) CaCl? (aq) + CO? (g) + H?O (l)

Preliminary Testing:

When doing this experiment the variable I changed was the concentration of the acid. The control in this experiment was the volume of hydrochloric acid which at the start I used 100ml yet after the preliminary I existingised if I needed 5 sets of results when doing the real experiment I would run out of resources so I cut the amount to 50 ml for the real experiment. I also tried to keep the same cant over of marble chips as even though it isnt completely...If you lack to get a full essay, order it on our website: Orderessay
