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. 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 teaching chemistry video series, a. 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.

Sodium thiosulphate and hydrochloric acid essay sample to investigate the effects of change in concentration on the rate of reaction between sodium thiosulphate and hydrochloric acid. If a very small amount of sodium thiosulphate solution is added to the reaction mixture (including the starch solution), it reacts with the iodine that is initially produced, so the iodine does not affect the starch, and there is no blue color. Conclusion in this experiment, i was able to test the collision theory, the kinetic theory and the reaction rates with high success, however, i looked over the results and realized that there was a huge amount of inconsistency with the reaction times, especially with peter’s results compared with mine. Lab activity 3 the effect of concentration changes on reaction rate the course of the reaction between sodium persulphate (na2s2o8) and potassium iodide (ki) solutions can be followed by adding small quantities of starch and sodium thiosulphate (na2s2 o3) to the reaction mixture.

Rate of reaction between sodium thiosulphate courswork chemistry idocx from experiment 3 of temperature change support the chemical idea that the rate of reaction increases as temperature increases which documents similar to rate of reaction between sodium thiosulphate courswork chemistry idocx. 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. 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. 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.

The reaction time can represent how long it takes to form a fixed amount of gas in the first few minutes of a metal carbonate-acid reaction, or the time it takes for so much sulphur to form in tin sodium thiosulphate-hydrochloric acid reaction. Iii chemical kinetics iii1- the iodine clock reaction this reaction rate is a measure of how much iodine was produced in the time it took for the account for all dilutions in the sodium thiosulfate solution concentration once you have determined m = [][ ] ki 1 5. 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.

- 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. Other suitable reactions to study the effect of concentration on the rate of reaction the effect of concentration of a dilute acid on the rate of reaction involving the liberation of a gas such as the reaction between a reactive metal (mg/al/zn/fe) and a dilute acid (hcl/h 2 so 4 ) to liberate hydrogen gas, a carbonate salt and a dilute acid. 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. The rate of a chemical reaction is the rate at which reactants are used up or products are produced in order to measure the rate of reaction we measure the amount of reactants used or products produced over a certain period of time.
