Sodium thiosulphate and hydrochloric acid coursework conclusion

Introduction this is an investigation about the decomposition of sodium thiosulphate there are many factors (variables) which determine how fast or slow the reaction can take place (rate of reaction) these are: initial volume of sodium thiosulphate the initial volume of hydrochloric acid the initial volume. My coursework is based on rates of reaction concentration of sodium thiosulphate and react it with hydrochloric acid and see analysis of trial run: during the first trial run i changed the volume of sodium thiosulphate in ml and water also in ml i chose to measure in ml because the concentrations of the fluids are best. Rate of reaction between sodium thiosulphate and hydrochloric acid aim === during my investigating, i am going to investigate the factors that effect the rate of reaction between sodium thiosulphate and hydrochloric acid background information the key variables in this experiment are: concentration the reaction rate.

Investigate what happens to the rate of reaction when the concentration of sodium thiosulphate is altered in the reaction between sodium thiosulphate and hydrochloric acid rates of reaction investigation aim the aim of this coursework is to investigate what happens to the rate of reaction when the concentration of.

To study the reaction rate during the reaction between sodium thiosulphate and hydrochloric acid • optional: to determine the order of a reaction didactical approach when a sodium thiosulphate solution reacts with hydrochloric acid, a precipitate of sulphur is formed: na2s2o3 (aq) + 2hcl(aq) → 2nacl(aq) + so2 ( aq). The hydrochloric acid - sodium thiosulphate reaction depends on the time for a certain amount of sulphur precipitate to form and obscuring a marked black x on white paper briefly explain how the method can be used to measure the speed - the results of the first few minutes is usually the most crucial - you can discuss. (1) a measuring cylinder was used to measure 50cm3 of 008m sodium thiosulphate solution into a test tube a bung (5) the sodium thiosulphate and hydrochloric acid in the test tubes were poured into the beaker and the (9) use your graph to draw a conclusion about the change of the rate of reaction with temperature. Aim my aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate i will be timing and watching: how quickly the reactants are used up how quickly a product is formed the rate of reaction (ror) describes how fast a reaction.

In this piece of coursework, i will study how concentration affects the rate of reaction i will do so by timing the reaction of sodium thiosulphate with an acid in this coursework, i will include background knowledge, prediction, safety, results, calculations, graphs, an analysis, conclusion and an evaluation in my evaluation i. Conclusion a novel pbl chemistry laboratory course for pharmacy students was successful in that self-reflective learning and engagement with hydrochloric acid, 7 m, 5 ml x3 6 titrate immediately with 01 m sodium thiosulphate using 1 ml of starch solution as indicator, added towards the end of.

The reaction between magnesium metal and hydrochloric acid is suitable for this particular experiment the concentration of hydrochloric acid can easily and safely be adjusted by adding water to the solution the reaction produces a gas, so the reaction rate can easily be determined by measuring the amount of gas.

  • There will not be any coursework in the gcse (9–1) science qualifications this question requires students to justify a conclusion by comparing two pieces of acid and marble chips) b observing a colour change (in the reaction between sodium thiosulfate and hydrochloric acid) this investigation is in two parts.
  • The reaction time can represent how long it takes to form a fixed amount of gas in eg in the first few minutes of a metal/carbonate - acid reaction, or the time it takes for so much sulphur to form in the sodium thiosulphate - hydrochloric acid reaction the time can be in minutes or seconds, as long as you stick to the same unit.
