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.

    Mass of carbonate: This is the factor that I have chosen to vary. It will provide a suitable number of results for the experiment. The carbonate used will be calcium carbonate, and the acid will be 2 molar hydrochloric acid.

  2. The Factors Affecting the Volume of CO2 released when a Carbonate reacts with an ...

    When testing for one variable, all the other variables must remain constant. I know that tests which produce higher volumes of CO2 have greater accuracy. This is because the percentage of inaccuracy is much smaller when large values are used rather than when small values are used.

    I have purposely chosen 0.5g as it is in the centre of the range. My actual results table should hopefully look like the one shown over the page. My table for the preliminary results is different to the table of the actual results.

    After setting up the apparatus, I will measure 1 gram of medium sized calcium carbonate (to two significant figures) on a piece of paper on the balance, the paper is there so the calcium carbonate can easily be transferred without losing some of the calcium carbonate.

    The temperature was kept at room temperature which was 20�C which is 75�F. Measurements All measurements must be done at eye level, for example when measuring 20ml hydrochloric acid; you have to go down to eye level of the 20ml mark and slowly pure in the hydrochloric acid to this volume.

  2. Determine the concentration of lime water.

    = 8.12gdm3 Evaluation My practical experiment went quite well and I got a variety of results, which were suitable for the task given. My results show that I got two identical results and one just 1.1cm3 off. Which suggests that I have been accurate and precise during the experiment.

    is not as it displaces the water. The preliminary work was done for me to decide reasonable values for the volume of hydrochloric acid used and the size of the marble chips, i.e. the variables. For both variables I recorded the time it took for 50cm3 of carbon dioxide gas to be produced.

  2. Investigate the factors, which affects how quickly Calcium carbonate reacts with hydrochloric acid.

    The successful collisions are the one where the particles hit head on and the particles contain high energy and this by increasing the temperature. Fig2 raising the temperature speeds up a reaction This explains why I have made the prediction I have made.
