Aim
I am going to investigate the effect of concentration on the reaction between hydrochloric acid and calcium carbonate. I will also investigate the effect the variables will have on the rates of reaction. ... Concentration of the hydrochloric acid- the greater the concentration of the hydrochloric acid the faster the rate of reaction this is because of there being more hydrochloric acid particles to collide with calcium carbonate particles
2. Temperature- the higher the temperature the faster the rate of reaction this is because the hydrochloric acid particles will move more rapidly than in a low temperature
3. Size of particles- if particles are broken down it will give a greater surface area meaning collision to be more frequent increasing the rate of reaction
4. ...
Prediction
I predict that the higher the concentration of hydrochloric acid, the quicker the rate of reaction. ... When they come together, if the hydrochloric acid is more concentrated then there will be more hydrochloric acid particles to collide with the calcium carbonate particles therefore making the rate of reaction quicker because the particles are colliding more frequently
Lower concentration Higher Concentration
The lower concentration diagram shows the calcium carbonate in a low concentration of hydrochloric acid.
