    Sodium Thiosulphate Investigation Aim: To investigate how the concentration of hydrochloric acid affect the rate of reaction. Background: Sodium Thiosulphate reacts with hydrochloric acid to form a yellow precipitate. The word equation for this is : Sodium Thiosulphate + Hydrochloric acid = Sodium Chloride + Sulphur + Water The chemical equation for this would be Na2S2O3 + 2HCl = 2Nacl + S + H2O + So2 When dilute hydrochloric acid (colourless) is added to sodium thiosulphate

    Sodium Thiosulphate & Acid Planning To ensure that this experiment is safe, I have taken some precautions. I wore goggles at all times, made sure not to spill any chemicals such as the acid onto skin or clothes, and to be aware of glass. I have used various different apparatus, including two measuring cylinders, one 25ml, and the other 50ml. I used a 150ml chronicle flask and a stopwatch. Here is a few diagrams of these apparatus. What I Will Vary, Not Change To Keep A Fair Test &

    The higher the temperature of the sodium thiosulphate the faster the reaction of the two liquids. Information. According to the kinetic theory all matter is made up of tiny, invisible particles that move all the time. When the temperature is increased around or on these particles, the faster they move. Heavier particles move more slowly than light ones at a given temperature. This theory defines the differences between solids liquids and gasses; in a gas the particles move freely and

    Rate of Reaction with Sodium Thiosulphate COLLISION THEORY The Collision theory of Reaction Rates is said by some to be one of the most stable in the Physical Sciences. The theory states that in order for a successful reaction to take place there must be 'effective' collisions between the reactant molecules. Simply having reactant molecules colliding is necessary but not sufficient in itself. The collisions have to be effective. Collision theory explains this reaction, in a concentrated

    Sodium Thiosulphate and Hydrochloric Acid Reaction Investigation Aim To see the effects of concentration on the rate of a reaction between sodium thiosulphate and hydrochloric acid. Background information The collision theory briefly: For a reaction to occur particles have to collide with each other. Only a small percent result in a reaction. This is due to the energy barrier to overcome. Only particles with enough energy to overcome the barrier will react after colliding. The

    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.

    The Reaction of Sodium Thiosulphate with Hydrochloric Acid Plan ==== I am going to investigate the rates of reaction when sodium thiosulphate reacts with hydrochloric acid. The rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a chemical reaction. It is measured by dividing 1 by the time taken for the reaction to take place: 1 [IMAGE] Seconds ------- There are five factors, which affect the rate of a reaction, they are:

    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 thiosulphate makes the reaction

    Reaction of Hydrochloric Acid and Sodium Thiosulphate In this investigation I am going to investigate how fast the chemicals Hydrochloric Acid and Sodium Thiosulphate react. The four main variables that affect rate are: * Temperature - if the reactants are heated/cooled they have more/less energy. If they have more energy there is greater chances of successful collisions meaning the reaction occurs faster. * Concentration - if the solution is more concentrated there are more reactants
