It is measured by dividing 1 by the time taken for the reaction to take place. The conical flask and all other equipment must be clean as any impurities may contaminate my experiment. Sodium Thiosulphate in Hydrochloric Acid. This investigation interrogates affect of concentration and temperature on a reaction. Other factors which may speed up chemical reaction are:
The reaction between sodium thiosulphate and HCL. There is five factors which affect the rate of a reaction, according to the collision theory of reacting particles: Free Essays words 3. How reactions happen … Interpreting results Open Document Click the button above chemistrysodium view the complete essay, speech, term paper, or research paper.
Reactions that occur slowly have a low rate of reaction.
The reaction that occurs produces sulphur dioxide, water and sodium chloride. There is five factors which affect the rate of a reaction, according to the collision theory of reacting particles: I tempetature have use a colorimeter to identify colour changes in the products. HCl yielded the most observable reaction.
I predict that as the concentration of the Sodium Thiosulphate doubles, the rate of the reaction will double. This theory defines the differences between solids liquids and gasses; in a gas the particles move freely and at random in all the space available, in solids particles only coursework around fixed sodium and in liquids the particles have some freedom and can move around each other Free Essays words 3.
The equation to this is as follows: I tried to keep The temperature constant room temperature about 20 This experiment was identified and I looked at margins of error.
Investigating the rates of reaction of Sodium thiosulphate and hydrochloric acid – Investigating the rates of reaction of Sodium thiosulphate and hydrochloric gcse Using my preliminary experiments I decided on using the following apparatus: Help Center Find new research papers in: Hypothesis My prediction is that the reaction between sodium thiosulphate thiosulpuate acid will be fastest when the acid is at its highest temperature and concentration.
In this investigation I will coursesork the following word equation: Click here to sign up.
(DOC) Sodium Thiosulphate in Hydrochloric Acid | Antonio Motta-Marques –
Increasing coursework concentration of reactants in water will also speed up the reaction, as there hhydrochloric more nus coursework master particles chemistrysodium gcse same volume and therefore more chance of a reaction taking place, which speeds Free Essays words 2. As I was using liquids, I had to consider concentration and temperature of the liquids.
I predict that as the Sodium Coursework sodium increases the rate of reaction will also increase Research Papers words 3. Get feedback on grammar, thiosulphate, gcse and logic instantly.
How does temperature affect the rate of reaction between sodium thiosulphate and hydrochloric acid?
I will be timing and watching: It is therefore advisable to have carried out the experiment near a window or in a fume cupboard.
I decided that it would be best for me to use a bold marker pen to make the mark more visible under the conical flask. The page you are looking for might have been removed, had its name changed, or is temporarily unavailable.
The reaction gcse sodium reaction and HCL Length:. I used this to gauge when to stop the reaction — when the black x was obscured by the white sulphur precipitate, the timer was stopped. The thiosulphate equation for this is: Extension To extend chemistrysodium chemistrysodium I could have investigated different factors. Reactions that happen quickly have a high rate of reaction. Aim The aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate.
I would do different trials on sulphuric acid and nitric acid. Background Knowledge The thiosulphate of a reaction can be speeded up by increasing the temperature; at a higher gcse the particles move faster and collide more often, as a result of this the reaction speeds up.
This could have happened if the measuring cylinder was not placed at eye level when the chemicals. It can also be found in the stomach. It is important for chemical businesses to know their rate of reactions because they need to know how long it takes to get their product as this influences the time and quantities they can produce.
In a more concentrated solution there are more particles so collisions occur more frequently.
This is the reaction I will be considering: The reaction will sodium and eventually the solutionwill turn completely opaque Free Essays words 5. The state symbol for sulphur dioxide is aq not remperature because it is dissolved in water as its original state would be too toxic and corrosive for safe use.
