  • The Effect Of Concentration And Temperature On The Rate Of Reaction Between Hcl And Sodium Thiosulphate And Hydrochloric Acid

    1298 Words  | 6 Pages

    (HCl) and Sodium Thiosulphate (Hypo solution). There are multiple ways to test the rate of reaction between two substances, however the experiment we will be conducting involves placing a conical flask directly over a black coloured ‘x’ and recording the time it takes for the ‘x’ to become invisible after the two solutions react with each other. This is simple and direct as multiple tests can be undertaken at different concentration levels and multiple temperatures. Sodium Thiosulphate and Hydrochloric

    Experiment 1 : Redox Titration Using Sodium Thiosulphate Abstract This experiment is to determine the concentration of oxidizing solution using the iodine/ thiosulphate titration where the reducing solution is potassium iodate solution and the oxidizing solution is sodium thiosulphate solution. Potassium iodate solution which is an oxidizing agent is added into an excess solution of acidified potassium iodide. This reaction will release iodine. Potassium iodide is acidified with sulphuric acid

  • Reaction Rates of Sodium Thiosulphate and Hydrochloric Acid Essay

    Reaction Rates of Sodium Thiosulphate and Hydrochloric Acid at Various Concentrations Introduction/ plan ------------------ I am experimenting into the reaction rates of Sodium Thiosulphate and Hydrochloric acid when under different concentrations. Both Sodium Thiosulphate and Hydrochloric acid are clear solutions but when they react together they produce a cloudy solution, the solution become so cloudy you cannot see through it. To measure the rate of reaction I am going to print

    EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

  • Investigating Reaction Rates of Sodium Thiosulphate and Hydrochloric Acid

    Investigating Reaction Rates of Sodium Thiosulphate and Hydrochloric Acid Aim: To investigate the rate of reaction of Sodium Thiosulphate and Hydrochloric acid. In this investigation I will be varying the concentration of Sodium Thiosulphate only and not the Hydrochloric acid concentration. In this investigation I will use the following word equation: Sodium Thiosulphate + Hydrochloric acid In this investigation I will use the following symbol equation:

  • The Effect Of Sodium Thiosulphate On Reaction Rate

    Title: The effect of Hydrochloric Acid volume with Sodium Thiosulphate on the reaction rate. Introduction: Research Question: How does changing the volume of Hydrochloric Acid on Sodium Thiosulphate effect the time taken for the ‘X’ Mark to dissapear? The rate of a chemical reaction is the time required for a given quantity of reactant to be changed to product. The unit of time may be seconds, minutes, hours, days or years. For a chemical reaction to occur it needs to have a collision, and it is

  • The Effect of Temperature on the Rate of Reaction Essay

    1241 Words  | 5 Pages

    The effect of temperature on rates of reaction Aim: The aim of this experiment is to find out if the reaction rate of sodium thiosulphate solution and hydrochloric acid will be affected by a temperature change. Prediction: I predict that as a result of increasing the temperature of the sodium thiosulphate, the rate of reaction will be faster. Because of the increase in temperature, the particles will gain more kinetic energy. This will therefore cause them to move faster and produce more successful

    rate of degradation so they could estimate how much Vitamin C should be made and when the expiry date should be. In this experiment a solution of Vitamin C is added to a solution containing of known excess of iodine. At this point, the solution will turn blue-black in colour and this excess amount of iodine can then be titrated against standardized sodium thiosulphate. (^citation here) This technique is called back-titration. The Iodine is produced by the mixture of the following reagents: KIO3,KI

    The Potassium Iodide particles will increase and the frequency of their collisions with Hydrogen Peroxide particles will also increase, causing them to react quicker. I hypothesize that as I increase the concentration of the Potassium Iodide Solution, the rate at which the blue-black starch complex covers the ‘X’ marking on the tile, will also increase until a point where the rate will remain the same due to all the particles having already finished reacting. 1
