Extracts from this document...


Calcium Carbonate + Hydrochloric Acid -> Calcium Chloride + Water + Carbon Dioxide CaCO3 + 2HCl -> CaCl 2 + H2O + CO2 Aim Investigate factors affecting rate of reaction between calcium carbonate and hydrochloric acid. Method & Diagram Fill measuring cylinder with water Half fill water basin with water Invert measuring cylinder whilst covering open end with hand Submerge measuring cylinder (End with hand on) Put 25ml of acid into the conicle flask Have 2.0g of marble chips ready Put end of pipe into submerged conicle flask Prepare to start stopwatch Put marble chips in with acid & put bung on conicle flask whilst starting stopwatch Every 30s starting from 0s take a measurement of how much air there is in measuring cylinder (cm3) When you have done this with the first concentration of acid clean out the conicle flask and refill the measuring cylinder & repeat experiment with next concentration of acid. ...read more.

2.0M acid was so fast compared to 0.5M acid because in 2.0M acid there is a higher concentration of particles of acid so there is more chance of a collision between acid particles and calcium carbonate particles. In 0.5M acid it was so slow because there is a quater of the amount of acid particles in 2.0M acid. I can draw a labelled diagram which shows particles of acid colliding with marble chips and making gas and I can use this to explain what I found out in my results. Evaluation I cannot think of a better way of doing the experiment or collecting more accurate results except than using more detailed measuring cylinder's. I do think that taking averages helps because it gives an average result which means that it can be more accurate than lots of individual results. The main difficulties in doing this experiment I think were taking results accurately. ...read more.
