Using the syringe method I am going to investigate the reaction
between Marble chips and hydrochloric acid by measuring the volume of
carbon dioxide formed. This reaction rate will tell me how fast or
slow a chemical reaction is and there are four things that could
affect this greatly they are-
* Concentration-An increase in concentration means there are more
particles. More particles mean that there will be more collisions.
* Surface area-When one of the reactants is solid; the reaction can
only take place at the surface of the solid. Breaking the solid
into smaller pieces will increase the surface area exposed to the
* Temperature-Since temperature is a measure of the motion of
particles, increasing temperature will cause the particles to move
faster, more collisions occur and the collisions are more violent.
This should increase the rate of reaction.
* Catalysts-Catalysts are substances that change the rate of a
chemical reaction without being changed in the reaction. Catalysts
are most often used to speed up the chemical reaction.
I tried to do some preliminary work but each time the reaction went
either to fast or to slow which meant in the experiment I wouldn't get
accurate results. I decided to use the same amounts of hcl acid and
water that I had used in class once before as I knew these results
would be accurate.
I will be using-10 cm3 Hcl acid with 40 cm3 water
9 cm3 hcl acid with 41cm3 water
8 cm3 hcl acid with 42 cm3 water
7cm3 hcl acid with 43 cm3 water
6cm3 hcl acid with 44 cm3 water
Im also using 10 g of small marble chips each time.
Using the collision theory I predict that the more concentrated the
acid, the more collisions so the quicker and more violent the reaction
To make this experiment a fair test I will make sure that the marble
chips will be of the same size, amount and mass. I want to make sure
that the marble chips are as similar as possible throughout the
experiment and hopefully the results will be in direct relationship to
each other. I will make sure that I use the...
