How does the concentration of sodium thiosulphate affect the rate of reaction coursework

Explaining the effect of size of a solid reactant/surface area on the rate of reaction using collision theory when the size of a fixed mass of a solid reactant decreases, the rate of reaction increases this can be explained using the collision theory, as below. When the concentration of sodium thiosulphate was increased the rate of reaction increased and the time taken to reach equilibrium decreased, so therefore the rate of reaction is directly proportional to the concentration. Incomplete question rate of which reaction, we can’t guess what the other ingredients are please edit your quest. To further investigate the decomposition of sodium thiosulphate i could change the concentration of hydrochloric acid and sodium thiosulphate or use a catalyst in the reaction overall i think that my investigation was successful in obtaining reliable results. The effect of concentration on the rate of reaction (i) take a tr ough and fill half of it with water this will serve as table 22 : the effect of temperature on the rate of reaction between sodium thiosulphate and hydrochloric acid volume of sodium thiosulphate solution used each time = 50 ml volume of hcl used each time = 5 ml sl no.

Investigating how the concentration of sodium-thiosulphate (sts) and hydrochloric acid (hcl) affects the rate of reaction in the experiment in addition i am also checking how different variables affect my experiment and also how i can make my test more precise, reliable and accurate. See thiosulphate problem solving network analysis acid coursework may 18, 2017 to insert how the how to come up with a essay topic of writing between rates of reaction coursework sodium thiosulphate poor and strategic acid is very by using the world. The higher the concentration, the more moles o it compared to water so, if there is kore of a reactant, the reaction happens quicker however, note that in the case of concentration, if it is halved/doubled the amount of product is also halved/doubled.

Gcse chemistry rates of reaction courseworkaim my aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphaterate of reaction of sodium thiosulfate and hydrochloric acid the purpose of this demonstration is to investigate the effect of sodium thiosulfate concentration on the rate of reaction of sodium. Differential rate laws express the rate of reaction as a function of a change in the concentration of one or more reactants over a particular period of time, they are used to describe what is happening at the molecular level during a reaction (mechanism-focused. The effect of increasing the concentration on the rate of a reaction can be shown by looking at the reaction between sodium thiosulfate solution and dilute hydrochloric acid.

Sodium thiosulfate solution is reacted with acid – a sulfur precipitate forms the time taken for a certain amount of sulfur to form can be used to indicate the rate of the reaction. 80 experiment starter sheet - investigating the rate of reaction between sodium thiosulphate and hydrochloric acid here is a suggested method to investigate the effect of varying the concentration. Introduction there are a few factors that affect the rate of reaction: temperature, reactant concentration, reactant surface area, pressure, the presence of catalyst and the physical states of. The rate of reaction between sodium thiosulphate and hydrochloric acid candidate name: yeo jin kim (kimberly kim) candidate number: 000791-021 teacher: yitao duan 10 aim the aim of this experiment is to investigate the changing of concentration effect the rate of reaction between sodium thiosulphate and hydrochloride. If you are doing something like the hydrochloric acid - sodium thiosulphate reaction, your reaction time measures the formation of a fixed amount of sulphur per 'time' so the rate is 'x amount of sulphur per time', which means the speed or rate is proportional to 1/time, then plot this 1/time against the concentration of the acid.

In this experiment i will be seeing how the concentration of sodium thiosulphate, na2s2o3, and hydrochloric acid, hcl, affects the rate of the reaction in this reaction the solution turns milky yellow as sulphate is displaced and forms a solid precipitate. Therefore as the concentration of the sodium thiosulphate increases, the rate of reaction increases explanation one of the weakness of our experiment was that the person recording the time changed and this may be the reason for the slight deviation in our experiment. Jawaban terbaik: rate of reaction - sodium thiosulphate and hydrochloric acid aim investigation, to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration introduction i must produce a piece of coursework investigating the rate of reaction. Aiminvestigation, to find out how the rate of reaction between sodiumthiosulphate and hydrochloric acid is affected by changing theconcentrationintroductioni must produce a piece of coursework investigating the rate ofreaction, and the effect different changes have on them.

How does the concentration of sodium thiosulphate affect the rate of reaction coursework

how does the concentration of sodium thiosulphate affect the rate of reaction coursework - the rate of reaction is high when the concentration of sodium thiosulphate, na2s2o3, solution is high concentration of sodium thiosulphate, na2s2o3, solution is directly proportional to 1/time or rate of reaction.

To study the effect of reactant concentration on the rate of the reaction between sodium thiosulphate and hydrochloric acid and to determine the order of sodium thiosulphate the reaction used in this experiment is between dilute hydrochloric acid and sodium thiosulphate (formula na2s2o3. - sodium thiosulphate rates of reaction aim: we must produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them the rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a chemical reaction. Rates of reaction coursework aim: to find out how different concentrations of sodium thiosulphate (na s2 o3) affects the speed of its reaction with hydrochloric acid (hcl.

  • Decomposition of sodium thiosulphate aim: the aim or purpose of this investigation is to explain how concentration affects the rate of reaction (the decomposition of sodium thiosulphate in reaction with hydrochloric.
  • For the hydrochloric acid - sodium thiosulphate reaction you can plot either (i) reaction time, or (ii) 1/time versus a concentration or temperature (1/time = relative rate of reaction) it is best, if possible, to have all the average results points plotted on the same graph for easy comparison - take care because this may involve 4 or 5 lines.

Gcse chemistry coursework: investigating the rate of a reaction your task is to plan, and carry out, an experiment to discover how to change the rate the reaction between sodium thiosulphate solution and dilute hydrochloric acid. This is a reaction which is often used to explore the relationship between concentration and rate of reaction in introductory courses (like gcse) when a dilute acid is added to sodium thiosulphate solution, a pale yellow precipitate of sulphur is formed. The rate of reaction between sodium thiosulphate and hydrochloric acid – chemistry iaa (concentration) sodium thiosulphate using a measuring cylinder and place into a clean labelled boiling tube 3) – keeping concentration of the liquids the same so it doesn’t affect rate of reaction and successful collisions. Chemistry rates of reaction coursework: sodium thiosulphate and hydrochloric acid simple procedure place a conical flask on a piece of paper with a cross on it add hydrochloric acid and sodium thiosulphate, and record the amount of time taken for the cross to disappear through the solution from the top of the flask.

how does the concentration of sodium thiosulphate affect the rate of reaction coursework - the rate of reaction is high when the concentration of sodium thiosulphate, na2s2o3, solution is high concentration of sodium thiosulphate, na2s2o3, solution is directly proportional to 1/time or rate of reaction.
