REACTION BETWEEN SODIUM THIOSULPHATE AND HYDROCHLORIC ACID COURSEWORK

I will be timing and watching: As I was using liquids, I had to consider concentration and temperature of the liquids. For example, when my concentration was 1M the average reaction time was seconds, and then when the concentration was 5M the average reaction time was seconds. Hi there, would you like to get such a paper? We’ll occasionally send you account related and promo emails.

I made sure that I had everything before I started. This can help me identify any faults. Hi, I am Sara from Studymoose Hi there, would you like to get such a paper? Your Answer is very helpful for Us Thank you a lot! Remember me on this computer. I predict that as the Sodium Coursework sodium increases the rate of reaction will also increase Research Papers words 3. Leave your email and we will send you an example after 24 hours

thoisulphate I drew 6 different graphs for this investigation. The room temperature could have affected my reaction and this could be the reason that I have some outliers.

I will discuss these further in my evaluation.

reaction between sodium thiosulphate and hydrochloric acid coursework

Activation energy Activation energy is the energy required to break the bonds of the reactants, so that new bonds sovium form to make the products. This could have happened because of human error, wrong calculations or simply not enough activation energy on that particular concentration.

The rate of reaction is the speed of a 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. This is very important because loose hair can not only get dipped into chemicals but can also obscure vision.

reaction between sodium thiosulphate and hydrochloric acid coursework

Thioosulphate enthalpy change is the amount of heat absorbed or released when a chemical reaction occurs at a constant pressure. Couraework 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.

The equation to this is as follows: This shows that there is no real difference between the results.

This is the reaction I will be considering: The bars for 3M, 4m and 5M do not overlap. The conical flask and all other equipment must be clean as any impurities may contaminate my experiment.

The reaction between Sodium Thiosulphate and Hydrochloric Acid.

When coursework temperature is increased around or on these particles, the faster they move. Science Experiments Coursework Rates Essays]. 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. Graphs All of the graphs that I drew for this investigation show a negative correlation.

If you need this or any other sample, we can send it to you via email. Variables An independent variable is one that is controlled by me, for example; the temperature, the time limit and mixing speed.

Investigating the rate of reaction between sodium thiosulphate and hydrochloric acid

This is supportive of my conclusion. Click chemistry button above to view the complete essay, speech, term paper, or research paper. This ensures that the solution is completely opaque when I stop the timer. This good because it shows that for every increase in concentration is a decrease in rate of reaction.

I predict that as the concentration of the Sodium Thiosulphate doubles, the rate of the reaction will double. Hypothesis My prediction is that the reaction between sodium ckursework and acid will be fastest when the acid is at its highest concentration. And supports my conclusion.

My conclusion is justifiable because I have backed it up with points from my data and I have proved all the points that I acjd. This shows that my data is quite accurate. Papers] Research Papers words 3.
