REACTION BETWEEN SODIUM THIOSULPHATE AND HYDROCHLORIC ACID COURSEWORK
The reaction gcse sodium reaction and HCL Length:. There is one outlier in 2M concentration. For example, rusting is a slow reaction; it has a low rate of reaction. I could test this by asking one of my peers to follow the instructions and then asking for their feedback. I made sure that I had everything before I started. 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 reaction that occurs produces sulphur dioxide, water and sodium chloride.
The room temperature could have affected my reaction and this could be the reason that I have some outliers. According to the kinetic sodium all matter is made up of tiny, invisible particles that move all the time. This increases the likelihood of reactants colliding properly and so increases the rate of the chemical reaction. This can help me identify any faults. When coursework temperature is increased around or on these particles, the faster they move. I then drew up graphs for my results Data Concentration Test Test 2 Test 3 M 1 s s s 1 2 3 4 5 Table 1:
Reactions that happen quickly have a high rate of reaction.
In a more concentrated solution there are more particles so collisions occur more frequently. I also made sure that the measuring cylinder was on a level surface so that I could clearly see how much liquid I was putting in to it.

We’ll occasionally send you account related and promo emails. Background Research Chemical reactions are to do with changing the materials that form the base of your experiment. These are circled on my graphs.
In a more concentrated solution there are more particles so collisions occur more frequently Recent updates The rate of reaction is the rate of loss of a reactant or the coursework thiosulphate formation of a product during a chemical reaction Free Essays words 6. We must produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them. Burning and explosions are very fast reactions: And supports sodiym conclusion.
I then drew up graphs for my results Data Concentration Test Test 2 Test 3 M 1 s s s 1 2 3 4 5 Table 1: The thiosulphate equation for this is: 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. Hi there, would you like to get such a paper?
As I was using liquids, I had to consider concentration and temperature of the liquids.
The dependent variable was hydrochloriv rate of reaction. Accessed May 22, The reaction that occurs produces sulphur dioxide, water and sodium chloride Free Essays words 4. Help Center Find new research papers in: As soon as the chemicals were in, I started the timer. This could have happened because of calculation errors, human errors, recording errors or a fault with the equipment that we used.
Hydrochloric acid is colourless, poisonous and highly acidic. My conclusion is justifiable because I have backed it up with points from my data and I have proved all the points that I made. If you contact us after hours, we’ll get back hydrchloric you in 24 hours or less. The independent variables in our experiment are the concentration of hydrochloric acid.
The rate of reaction between sodium thiosulfate and hydrochloric acid Essay
Papers] Research Papers words 3. Free Essays words 1. Essay on Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid – Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid In this experiment I am going to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration.
I had to make sure that my classmates were safe as well as myself. Research Papers words 4. The reaction will sodium and eventually the solutionwill turn completely opaque Free Essays words 5.
I will be timing and ckursework The points in the top right are quite far down so this shows a negative correlation. It is often used as a chemical intermediate and in petroleum production, food processing, pickling, and metal cleaning.
The results for 1, 2 and 4M keep showing outliers. There is one outlier in 2M concentration. This increases the likelihood of reactants colliding properly and so increases the rate of beyween chemical reaction.
