Sodium Thiosulphate Rates of Reaction During this investigation I am going to investigate the rates of reactions and which changes will affect this rate. A rate of reaction is when a reactant is lost or a new product is formed during a chemical reaction. I am going to investigate the effect of concentration by mixing Sodium Thiosulphate, Hydrochloric Acid and H2O (water) until the reaction takes place and the mixture goes cloudy and the newspaper beneath the flask can no longer be read
Concentration on Reaction Rate with Sodium Thiosulphate ---------------------------------------------------------------------- Planning ======== In this experiment I shall be varying the volume of sodium thiosulphate, hydrochloric acid and water, and measuring the reaction rate. When I increase the amount of sodium thiosulphate with less water, I think the time for the cross to disappear would be faster than there would be with little sodium thiosulphate and more water – taking in
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, and the effect different changes have on them. The rate of reaction is the rate of loss of a reactant or the rate of development of a product during a chemical reaction. It is measured by dividing 1 by
Rates of reaction:- sodium thiosulphate + hydrochloric acid Plan:- We must produce a piece of coursework investigating the rates of reaction, and the effect that changing one particular variable has on the reaction time. The rate of reaction is the time it takes one or more of the reactants to react or the time it takes to produce a new product from a chemical reaction. To work out the reaction time we use the formula. 1 divided by time taken for reaction There are five factors which
The Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid Theory: Sodium thiosulphate and hydrochloric acid, react together to produce sulphur as one of the products Na2S2O3 (aq) + 2HCl (aq) Sodium Thiosulphate + Hydrochloric acid à 2NaCl (aq) + H2O (l) + S (s) + SO2 (g) Sodium Chloride + Water + Sulphur + Sulphur Dioxide Sulphur is a yellow precipitate, so the solution will turn an opaque yellow colour while the reaction is occurring. The reaction will continue
The Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid Aim: I am going to investigate how changing the concentration of Sodium Thiosulphate affects the rate of reaction with Hydrochloric Acid. I am going to time how many seconds/minutes it takes until you can no longer see the black cross on a piece of paper under the beaker. Each time I do the experiment, I will change the amount of thiosulphate and water in the reaction mixture. I want to find out if the concentrated
Investigating the rates of reaction of Sodium thiosulphate and hydrochloric acid Using my preliminary experiments I decided on using the following apparatus: - A conical Flask - A piece of White Paper marked with a black cross - Dilute hydrochloric acid - Sodium thiosulphate - Water - Measuring cylinder 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
The Rate Of A Reaction Between Hydrochloric Acid And Sodium Thiosulphate Aim: I am going to investigate the effect of changing the concentration of Sodium Thiosulphate on the rate of the reaction between Hydrochloric Acid and Sodium Thiosulphate. Prediction: I predict that as the concentration of the Sodium Thiosulphate doubles, the rate of the reaction will double. I believe that when the most concentrated solution is used the reaction would be at its fastest. Collision Theory: In
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. In this coursework, I will include background knowledge, prediction, safety, results, calculations, graphs, an analysis, conclusion and an evaluation. In my evaluation I will comment on how reliable my results were and how I could have improved my coursework in any possible
An Investigation on the Rate of Reaction between Sodium Thiosulphate and Hydrochloric Acid Chemical Background When sodium thiosulphate is mixed with dilute hydrochloric acid it makes a cloudy liquid of sodium chloride, water, sulphur (this makes the liquid cloudy), and it gives of the gas sulphur dioxide. A precipitate of sulphur is made. Sodium + hydrochloric = sodium + water + sulphur + sulphur Thiosulphate acid chloride
The Effect of Temperature on the Rate of Reaction of Sodium Thiosulphate and Hydrochloric Acid Sodium chloride + Sulphur dioxide + Sulphur Plan The rate of reaction is the speed that the reaction occurs at. It can be effected by the following: * Concentration of reactants * Temperature * Surface area of reactants * Presence of a catalyst Out of those factors, I am going to investigate the effect temperature has on the rate of reaction. I will do this by recording
of acid affects the rate of reaction in the reaction between hydrochloric acid and sodium thiosulphate. Planning; Aim To see how the concentration of acid affects the rate of reaction in the reaction between hydrochloric acid and sodium thiosulphate. Background; All reactions occur because of the particles that make up the reactants will collide, and if they have sufficient energy, react forming or breaking bonds. All four methods of increasing the rate of reaction can be explained
The Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid Hypothesis: I believe that the resulting graph will like this: [IMAGE] · I know that the line will not go through the origin because at 0˚C the two chemicals are still liquid therefore they will still react together. · I believe that as the temperature increases the rate of reaction will also increase this coincides with the collision theory which states that as the temperature increases the speed of the
Investigating the Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid Aim --- I will be investigating the rate of reaction between Sodium Thiosulphate and Hydrochloric acid. I intend to find the difference in the rate of reaction when I change the concentration of the Sodium Thiosulphate, as I am only changing the concentration of the Sodium Thiosulphate I will keep the concentration of Hydrochloric acid the same at all times.

A chemical reaction can only occur between particle when they hit or collide
The Effect of Temperature on the Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid I predict that as the temperature is increased the rate of reaction will increase. This means that the graph drawn up in my analysis will have positive link so it will look something like shown below, and will probably be curved as the increase in rate of reaction will not be exactly the same as the temperature is increased so the graph will look something like this. [IMAGE] This can
How the Concentration of Sodium Thiosulphate Affects the Rate of Reaction with Hydrochloric Acid Plan We will set up a conical flask on top a cross. We will vary the concentration of Sodium Thiosulphate by putting different amounts of Sodium Thiosulphate and water bye keeping the same total volume of 50cm³. We will then add 5cm³ of hydrochloric acid. We will time how long it takes for the cross to completely disappear from site after the reaction has completely finished. Constants
