Chemistry coursework rate reaction sodium thiosulphate conclusion

I am going to investigate the rate of reaction between sodium thiosulphate (thio) and hydrochloric acid hydrochloric acid + sodium thiosulphate sodium chloride + water + sulphur the reactants are both colourless, but one of the products, sulphur, is yellow, so we can use this fact to follow the rates of reaction. The aim of my coursework was to test the rate of reaction how i could test the rate of rate of reaction is how quickly a product is made or reactants are used up the chemicals that were used were sodium thiosulphate and hydrochloric acid, as these chemicals are easy to handle the reaction to finish conclusion.

Enthalpy 2|page anjelina qureshi mrs gravell rates of reaction coursework chemistry year 11 enthalpy, in chemistry, is the heat content in a chemical reaction the enthalpy change is the amount of heat absorbed or released when a chemical reaction occurs at a constant pressure. The rate of the chemical reaction between dilute hydrochloric acid and sodium thiosulfate can be measured by looking at the rate of formation of solid sulfur.

In this coursework i will be investigating how sodium thiosulphate reacts with hydrochloric acid i predict that a decrease in the concentration of the reactant will result into a longer waiting time for the reaction to complete. Rates of reactions science (chemistry) coursework my coursework is based on rates of reaction this deals with the time taken for 1 draw an x on a piece of paper and pour 200ml of sodium thiosulphate and hydrochloric acid in different beakers. I am doing coursework on the rate of reaction between hydrochloric acid and sodium thiosulphate to avoid confusing i will describe the test i tried and then will tell the problems i had i took 20ml of both hydrochloric acid and sodium thiosulphate the hcl was 2 molar, the sodium t was 001 molar i used a conical flask and a delivery tube to take the gas formed into a tube of water to.

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. Physical & theoretical chemistry supplemental modules (physical and theoretical chemistry) the quantity 1/t can again be plotted as a measure of the rate, and the volume of sodium thiosulphate solution as a measure of concentration alternatively, relative concentrations could be plotted during the course of the reaction, as hydrogen. In this experiment the effect of temperature on the rate of reaction between sodium thiosulfate and hydrochloric acid is investigated hands-on practical activities or ideas for front of class demonstrations hands-on practical activities or ideas for front of class demonstrations. 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. Rate of reaction/f5/hst hst/rate of reaction/smkpb 15 1 plot the graph of (i) temperature against time and (ii) temperature against 1/time 2 based on your graph, what is the relationship between rate of reaction with temperature 3 write a balance chemical equation for the reaction of this experiment.

Rates of reaction - sodium thiosulphate and hydrochloric acid 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. Anjelina qureshi mrs gravell rates of reaction coursework chemistry year 11 rates of reaction introduction a chemical reaction occurs when things change from reactants into products these reactions only happen if the reacting molecules collide properly the rate of reaction is the speed of a reaction when the solution is made more concentrated, there are a greater number of molecules in the. Measuring the rate of reaction by disappearing cross sodium thiosulfate and hydrochloric acid kinetics study on the reaction between sodium thiosulphate and rate of reaction of sodium. Temperature of the reaction were not constant, it will affect the rate of reaction in each of the reaction with sodium thiosulphate, i used10 cm 3 of 10 mol dm -3 hydrochloric acid. 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.

The reaction between sodium thiosulphate and hydrochloric acid the effect on the concentration on the reaction between sodium thiosulphate and hydrochloric acid our aim in this investigation is to find out how the concentration of sodium thiosulphate affects the rate at which it reacts with hydrochloric acid. 2) the reaction between sodium thiosulphate can be shown in the ionic equation: i2 (aq) + 2s2o32-(aq) 2i-(aq) + s4o62-(aq) as the ratio of iodine to sodium thiosulphate is 1:2, i must therefore divide the number of moles i get in step 1 by two in order to work out the number of moles of iodine that reacted with the sodium thiosulphate. Gcse chemistry - sodium thiosulphate coursework 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 between sodium thiosulphate and hydrochloric acid aim the aim is to find the effect of different concentrations on reaction rate.

  • 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.
  • 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.

In the proper experiment, 30ml of water will be mixed with 20ml of sodium thiosulphate instead of 20ml of water with 30ml of sodium thiosulphate this should make the reaction slightly slower, thus easier to record, meaning that at higher temperatures the results should be more accurate. With over 20 years of trust in our products, the international boating community knows that when it comes to a mount for electronics, they choose ‘a scanstrut. Rate of reaction experiment - sodium thiosulphate and hydrochloric acid to investigate the effect, of changing the concentration of a reactant, in a chemical reaction on it rate.
