investigate the factors that affect the rate at which Sodium Thiosulfate (Na2S2O3) reacts with Hydrochloric Acid (HCl). When sodium thiosulfate is mixed with hydrochloric acid, a reaction takes place, leading to a precipitate of sulphur being formed. This turns the solution cloudy. I shall use this clouding to investigate a factor that affects the rate of reaction, the factor being temperature. To do this, I shall react Sodium Thiosulfate with Hydrochloric Acid at a range of temperatures
concentration of sodium thiosulfate and the time take for the cross to be no longer visible on the white tile through the solution. From graph 1 it could be seen that the concentration of sodium thiosulfate and the time taken for the reaction to be completed are inversely proportional, as when the concentration of sodium thiosulfate increases, the time taken decreases and the graph levels out as it approached the x-axis. Graph 2 supports this by showing that the concentration of sodium thiosulfate and the
How Temperature Affects the Reaction between Sodium Thiosulphate and Hydrochloric Acid Aim I am going to investigate the reaction between sodium thiosulphate and hydrochloric acid. The main aim is to find out how temperature affects the reaction; if it speeds it up, slows it down or changes it in any way. I will test the effects of temperature by timing how long it takes for a black cross to become non-visible underneath a beaker containing the reactants. I will consider what effect the
The Relationship Between Reaction Rate and Concentration I am going to investigate how varying the concentration of Sodium thiosulphate solution affects the rate of reaction with Hydrochloric Acid. The equation for the reaction is: [IMAGE]Sodium thiosulphate + Hydrochloric Acid Sodium Chloride + Water + Sulphur + Sulphur dioxide [IMAGE]Na2S2O3(aq) + 2HCl(aq) 2NaCl(aq) + H2O(l) + S(s) + SO2(aq) This reaction has a definite end (when the
concentration affects the rate of reaction. We used sodium thiosulphate (Na2 S2 O3) as our concentrated solution, hydrochloric acid and water to carry out our experiment. We did the experiment with two concentrations of sodium thiosulphate, 40gpl and 25gpl, to see which we would use for our main investigation. On a two pieces of paper, we drew a cross and place a beaker on top of the crosses. Into the beakers we poured 25cm3 sodium thiosulphate, the 40gpl solution in one and the 25gpl
determine the quantity of sodium hypochlorite found in a bleach product. This experiment allowed it to determine how much oxidizing agent is in a cleaner by using a redox reaction, which is a reaction involving the transfer of electrons from the compound being oxidized to the compound being reduced. To determine the amount of oxidizing agent, it is necessary to accurately measure out known amounts of redox reactants, know the stoichiometry
rate of which precipitate is formed when reacts with sodium thiosulphate. Prediction I think that a faster reaction will happen with a higher acid concentration as there will be more successful collisions with sodium thiosulphate, which will result in a faster reaction because the product will be produced quicker.

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.

Method: Apparatus Hydrochloric Acid Sodium Thiosulphate Distilled Water 250cm ³ Beaker- I need a beaker big enough to see the cross and although the 100cm³ would be perfect volume wise I would prefer to use a bigger one so I can fit the cross under it and also be able to pour
Identifying Five Unknown Chemicals I was given 5 unknown samples, which are sodium chloride, sodium thiosulfate, calcium carbonate, sodium bicarbonate and sodium nitrate and these samples are all white and solid. However, I don’t know which substance is which sample and I was only given some information about the physical and chemical properties of these substances. In order to identify the 5 unknown samples, knowing which sample is which substance, I have to carry out this experiment,
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
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
