The reaction gcse sodium reaction and HCL Length: The enthalpy change is the amount of heat absorbed or released when a chemical reaction occurs at a constant pressure. In my scatter graph with line of best fit, most of the points are close to the line. This fits in with my hypothesis and my data. If you contact us after hours, we’ll get back to you in 24 hours or less.
Rate of Reaction and Specific Rate Constant. For example, rusting is a slow reaction; it has a low rate of reaction. Conclusion In my investigation, my data and my graphs proved that my hypothesis was correct.

What factors affect the rate pf reaction between sodium thiosulphate and hydrochloric acid?
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 rate of reaction is the speed of a reaction. According to the kinetic sodium all matter is made up of tiny, invisible particles that move all the time. My data was precise because most of the points on my graphs are close to the line and are all close by each other.
Aim My aim is to investigate how changing the concentration of ad can thiosulphste the rate of reaction between hydrochloric acid and sodium thiosulphate. Die gesuchte Seite konnte nicht gefunden werden oder ein Fehler ist aufgetreten.

Sodium Thiosulphate + Hydrochloric Acid Coursework – GCSE Science – Marked by
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. 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: It thiiosulphate often used as a chemical intermediate and in petroleum production, food processing, pickling, and metal cleaning.
Your Answer is very helpful for Us Thank you a lot! I drew 6 different graphs for this investigation.
If I do a further investigation, I will try to minimise the number of mistakes that I make.
Rates of reaction vary depending on which chemicals are being used and the activation energy required. Reactions that occur slowly have a ocursework rate of reaction. How to cite this page Choose cite format: Sorry, but copying text is not allowed on this site.
The rate of reaction between sodium thiosulfate and hydrochloric acid Essay
We’ll occasionally send you account related and promo emails. I have used reliable resources to research this information and it all jydrochloric my conclusion.
The state symbol for sulphur dioxide is aq not g because it is dissolved in thjosulphate as its original state would be too toxic and corrosive for me to use safely. Reactions that happen quickly have a high rate of reaction. Sodium Thiosulphate reacts with hydrochloric acid to form a yellow precipitate. I believe that when the most concentrated solution is used the reaction would be coursework coursework fastest.
To do this I would make sure that: There is one outlier in 2M concentration. Dependent variables are not controlled by the experimenter.
(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –
It is measured by dividing 1 by the time taken for the reaction to take place. I think this because there is outliers in the 2M set of data and the thiosulohate bars overlap between 1M and 2M on my error bar graph. And supports my conclusion.
