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 a more concentrated solution there are more particles so collisions occur more frequently. The more often they collide the faster they react. This means that the rate of reaction will increase if the concentration of the reactants is increased. As shown below: Key= Sodium Thiosulphate Hydrochloric Acid Less concentrated solution More concentrated solution Independent Variable The variable that I am going to change is the concentration of Sodium Thiosulphate. Dependent Variable The dependent variable is the time in which the solution becomes cloudy thus hiding the X. Controlled Variables The controlled variables are the temperature, concentration of the acid, volumes of the Sodium Thiosulphate and the Hydrochloric Acid, Agitation/stirring. A factor which may change my results could be how I perceive that the X is marked. Summary Method My investigation is how the concentration of Sodium Thiosulphate will affect the rate of reaction. I will be using a range of concentrations from 10cm to 50cm to make it easier to see the difference in a graph. I then have to record the time taken for the reaction to finish. Once I have completed the 5 experiments I will use a table to gather my results and a graph to interpret them. However before I gather my results I will repeat the experiments for reliability and accuracy. Apparatus/Equipment The following apparatus is what I need for this experiment: * 3 measuring cylinders * 2 conical flasks * 1 stopwatch
Furthermore, using a graduated cylinder with markings below the 100 mL line would have allowed for more accurate measurements of the initial volume of air in the graduated cylinder.

The Effect of Sodium Thiosulphate Solution on the Rate of its Reaction with Hydrochloric Acid
Effect of Temperature on the Rate of Reaction between Sodium Thiosulphate and Hydrochloric Acid Investigation Chemical reactions are used in our everyday life, they literally keep us alive. They are used in food, respiration and everywhere else in the environment. A chemical reaction mainly occurs when reactants react together to produce a new product. The speed at which this reaction takes place is called the rate of reaction. The product produced has a number of particles in the solution that has formed from the reactants.
Investigating the reaction Between Sodium Thiosulphate (Na2S2 O3) and Hydrochloric acid (HCl) Aim --- I am investigating the rate of reaction between Hydrochloric acid (HCl) and Sodium Thiosulphate (Na2S2O3), when Na2S2O3 is mixed with water (H20). Background Knowledge The rate of a reaction can be speeded up by increasing the temperature; at a higher temperature the particles move faster and collide more often, as a result of this the reaction speeds up. Increasing the concentration of reactants in water will also speed up the reaction, as there are more reactive particles in the same volume and therefore more chance of a reaction taking place, which speeds up the reaction. This is shown in the diagrams below.
The Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Planning. CaCO3 (s) + 2HCl (aq) ---- CaCl2 (aq) + H2O (l) + CO2 The rate of reaction depends on how hard and how often the reacting particles collide with each other. A rate of reaction is how fast a reaction takes place.
Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Plan: In my experiment I will measure the rate of reaction between calcium carbonate and hydrochloric acid. The rate of the reaction is the speed that the reaction takes place so by measuring the rate I will measure the amount of time the reaction takes. Hydrochloric acid is a strong acid that is found in digestive juices in the stomach, it is also used for cleaning metals before they are coated. Calcium carbonate has a few forms including chalk and limestone the main use of these two materials is in the making of concrete, which is used for many things such as buildings. When you put calcium carbonate and hydrochloric acid together they react to form calcium chloride, carbon dioxide and water.
Investigating the Effects of Temperature on the Rate of Reaction between Magnesium and Hydrochloric Acid
The Effect of Temperature on the Rate of Reaction of Sodium Thiosulphate and Hydrochloric Acid
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 the time taken for the reaction to take place.
