OCR TITRATION COURSEWORK
With the help of computer-interfaced pH probes, you will investigate the qualitative and quantitative aspects of acid-base reactions. This concentration can then be calculated. Method Use a pipette and pipette filler to add 25 cm 3 of alkali solution to a clean conical flask. Investigate the rate of reaction of sodium thiosulfate with acid at different temperatures. Hey TSR i was just wandering if any of you could give me some urgent help on my recently set chemistry AS coursework. The actual colour change depends on the type of indicator used. Wear gloves and eye protection, and use a pipette filler.
Some of my worksheets for practical work are here. Chemistry a2 coursework – – you want write essay? Error – Page Not Found. Adding slightly different volumes of alkali to the flask will result in a systematic error. It is important in this practical activity to use appropriate apparatus and methods. Acceptable concentrations for the reagents are below 0. Chemistry is a huge subject and it covers.
Quantitative Task Record your titration results.

Analysis Example Calculate the mean titre. Investigate how the rate of a reaction changes with temperature. There are a number of ways that you could carry out a titration in Chemistry. It is possible to record results to the nearest 0. Chemistry AS-level Titration coursework Aim: Fill the burette with dilute acid. Determine the Mr of a volatile liquid or the Mr of a gas. For some synthesised chemical compounds – pharmaceuticals, for example – it is very important.
Published on Sep 9, Mathematical calculation of the pH change as base is added to acid, shows that there is a large change in pH near the neutralisation point end-point of the titration.
This chemistry laboratory resource shows what titration is and how this technique can be carried. To obtain valid results, it is important that measurements are precise and accurate.
Do a rough titration really quickly, get the value then slowly drip it isnt straight. Add a few drops of a suitable indicator ocursework put the conical flask on a white tile.
Stop adding the acid when the end-point is reached when the colour coursewor, permanently changes. All of the percentage inaccuracies may be added in a procedure and converted back to an absolute inaccuracy of the final ‘answer’.
