An experiment was carried out to investigate the effect of temperature on the rate of reaction between sodium (5) the sodium thiosulphate and hydrochloric acid in the test tubes were poured into the beaker and the timer (9) use your graph to draw a conclusion about the change of the rate of reaction with temperature. Disappearing x experimentintroductioni am going to investigate the rate of reaction between sodium thiosulphate (thio) and hydrochloric acid acid method, results, fair testing, evaluation included we then decided to change the experiment to see if the concentration of the acid affected the rate of reaction to do this. Read this full essay on the effects of change in concentration on the rate of reaction between sodium thiosulphate and hydrochloric acid gcse science this means that the graph drawn up in my analysis will have a negative correlation, because as one variable increases the other one decreases in this case as. Preliminary test 2 13-14 main experiment 15-17 main experiment results 17- 19 main experiment conclusion 19-21 main experiment evaluation 21-22 concentration of sodium thiosulphate and react it with hydrochloric acid and see 4 pour 20ml of sodium thiosulphate and 5ml of hydrochloric acid into a 25ml.
Introduction in this activity, learners can investigate the effect of concentration on the rate of reaction between hydrochloric acid and sodium thiosulfate this resource is adapted from the cleapss experiment 'the thiosulfate-acid reaction ' – http://wwwcleapssorguk/ attachments/ article/ 0/ thio_acid_rate_ase2014pdf.

Equipment: laminated paper with x on it beaker/test tube hydrochloric acid sodium thiosulphate solution conical flask/beaker stopwatch plan “ changing concentration analysis of results the basic pattern of the results shows that the more water that was added to the formula hcl (ml) 10ml 40cm3 hcl.
But before this i carried out a trail experiment to see which solution, sodium thiosulphate or hydrochloric acid would be more suitable my trail experiment method was to first collect all of the equipment needed, then i measured out the right amounts of each solution by measuring from the bottom of the meniscus [ tags:. Microsc acta 1979 jul82(1):53-8 hydrochloric acid-sodium thiosulphate-schiff reagent and its cytochemical properties dutt mk cytochemical properties of modified schiff reagent, prepared with 5 ml of n hcl and 10 g of sodium thiosulphate, the latter replacing potassium metabisulphite, have been presented in this. A great way to learn about chemical reaction rates is to perform a classic experiment called the disappearing 'x' experiment this classic experiment involves the reaction between sodium thiosulfate and hydrochloric acid, and teaches us much about reaction rates but before we can get into the experiment, we need to.
The methods provided in this required practical handbook are suggested examples, designed to help your students fulfil the apparatus and techniques requirements sodium thiosulfate solution (02 m) sulfuric acid (008 m) sulfuric acid (10 m) risk assessment safety is an overriding requirement for all practical work. Vary the concentrations of reactants and measure the time it takes for product to appear this video is part of the flinn scientific best practices for teach.
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). Some examples the examples on this page all involve solutions changing the concentration of a gas is achieved by changing its pressure this is covered on a separate page the reaction between sodium thiosulphate solution and hydrochloric acid this is a reaction which is often used to explore the relationship.
