Chemistry coursework rate reaction hydrochloric acid marble chips

Investigating Rate of Reaction Aim I am going to investigate the rate of reaction between calcium carbonate and hydrochloric acid. I also predicted that the increase of concentration would quicken the time for the reaction to take place.

The collision theory helps explain this because it says that the higher the concentration of acid, the more chance of an acid particle colliding with a marble particle, hence the quick rate of reaction.

You can see that the highest amount of concentration is 50 Cm3, which also has the quickest rate of reaction.

calcium carbonate and hydrochloric acid lab report

Temperature 2. Ranges of readings I think that my rage of results are fine, because if you were to go over this range then it would be too much and the reaction would take place too quick. Background Knowledge: I know from my knowledge of science, that by adding together a carbonate and an acid, that a salt, water and Carbon Dioxide are produced.

the rate of reaction of calcium carbonate with hydrochloric acid

Just from looking at the aim of the investigation I already know that a salt would be formed because a carbonate with an acid forms a salt. Catalyst 4. If the reaction takes too long to finish then I will have to shorten the rate of magnesium that I use, however if the reaction is too short then I will have to do the marble and increase the reaction of magnesium that I use.

In order for a reaction to occur certain things are necessary:. These are the kind of results I expect to approximately get, on the day of the experiment. But to make them much more accurate I could of done one of the following things: Take more readings and then find the average Use marble powder because some chips have bigger surface area then others and could affect the results.
