RATE OF REACTION COURSEWORK SODIUM THIOSULPHATE AND HYDROCHLORIC ACID
The reaction between sodium thiosulphate and HCL. The reaction that occurs produces sulphur dioxide, water and sodium chloride Free Essays words 4. 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. Sodium Thiosulphate reacts with hydrochloric acid to form a yellow precipitate. This makes sure that my experiment runs smoothly. Hydrochloric acid is colourless, poisonous and highly acidic.
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. Reactions that occur slowly have a low rate of reaction. This energy gives the reactant particles enough energy to collide with enough force to break apart the bonds so that new products can be made from atoms. My data has proven to be reliable and I am therefore happy to use it to make a justifiable conclusion that concentration does have an effect on rate of reaction. I wrote down my results and then moved on to the next concentration of sodium thiosulphate. Remember me on this computer. The points in the top right are quite far down so this shows a negative correlation.
Rate of Reaction – Sodium Thiosulphate and Hydrochloric Acid
Nobody in my group was nydrochloric but if they were, I would have carried out the experiment near a window or in a fume cupboard.
The reaction that occurs produces sulphur dioxide, water and sodium chloride Free Essays words 4. 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.
The reaction gcse sodium reaction and HCL Length:. Reactions that occur slowly have a low rate of reaction.
I coursework on linkedin going to investigate the effect of chemistrysodium the concentration of Sodium Thiosulphate on the rate of the reaction between Hydroculoric Acid and Sodium Thiosulphate.
Research Papers words 4. Burning and explosions are very fast reactions: There is one outlier in 2M concentration.
I think this because there is outliers in the 2M set of data and the error bars overlap between 1M and 2M on my error bar graph. 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: This is because when there are more molecules in the solution, there are more molecules to collide so this will speed up the reaction, and therefore it is more likely they will collide with each other.
I could test this voursework asking one of my peers to follow the instructions and then asking for their feedback. The reaction between sodium thiosulphate and HCL.
(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –
And supports my conclusion. This fits in with thiosluphate hypothesis and my data. Remember me on this computer. The equation to this is as follows: When the solution is made more concentrated, there are a greater number of molecules in the same space.
Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate. This is because there will be more acid molecules in the same amount of solution, therefore more effective collisions with the sodium thiosulphate, and the rate will be higher.
This increases the likelihood of reactants colliding properly and so increases the rate of the chemical reaction. These two acids react well with the right materials.
This ensures that the solution is completely opaque when I stop the timer. Hydrochloric acid is colourless, poisonous and highly acidic. The reaction gcse sodium reaction and HCL Length: Heavier particles move more slowly than light ones at a given temperature. When coursework temperature is increased around or on these particles, the faster they move.
This theory defines the differences between solids liquids and hydrochlpric 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. Papers] Research Papers words 3. Using white paper helped the marking to stand out.
Keep the size of my measuring flask is the same size; this should couursework make my experiment much fairer and accurate. Free Essays words 1.
