Datalogging experiment (2) 38 kinetics of iodination of propanone by colorimetry student handout purpose to determine the rate equation of the reaction between acidified propanone solution and iodine introduction as the following reaction proceeds ch3coch3(aq) + i2(aq) --→ ch3coch2i(aq) + h+(aq) + i-(aq. Introduction: chemistry of the reaction: propanone and iodine react together in an irreversible redox reaction to form iodopropanone this reaction is catalysed by aqueous hydrogen ions (protons) produced from the sulphuric acid as the reaction proceeds the dark brown colour of iodine in solution gradually turns.
Risk assessment of iodine and propanone reaction - download as word doc (doc / docx), pdf file (pdf), text file (txt) or view presentation slides online.
The chemistry b (salters) coursework marking descriptors have been devised to allow a wide variety of types of investigation kinetics of the reaction between propanone and iodine in acid solution first use a colorimeter to find the order of reaction with respect to propanone, iodine and acid therefore find rate equation,. The background theory is outlined, including the need to obtain a calibration graph the technique is then used to investigate the kinetics of the reaction in which iodine and propanone react in the presence of dilute hydrochloric acid the latter is an excellent reaction for considering how the order can be.
Kinetics of the acid catalysed reaction between iodine and propanone i shall base my investigation around the following reaction: i2(aq) + ch3coch3 (aq) ch3coch2i (aq) + h⁺ (aq) + i⁻ (aq) aims of the investigation by the end of this investigation i hope to have worked out the rate equation and the rate constant for. Finding orders of reaction experimentally this page is an introduction to some of the experimental methods that can be used in school labs to find orders of reaction there are two fundamentally different approaches to this - you can either investigate what happens to the initial rate of the reaction as you.
We've done an experiment iodine reacts with propanone the reaction mixture contains -50 cm3 of 002 m i2 in aqueous ki solution -25 cm3 of h2so4 -625cm3 o.
