RATE OF REACTION BETWEEN SODIUM THIOSULPHATE AND HYDROCHLORIC ACID COURSEWORK

I believe that when the most concentrated solution is used the reaction would be coursework coursework fastest. Use of rate of reaction in industry The chemical industry makes medicine and many other substances such as; Limestone – this is used for building Sulphuric acid — used to make other substances Ammonia – used to make fertilisers. We must produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them. The equation to this is as follows: 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.

I drew 6 different graphs for this investigation. On my ROR graph, there is a positive correlation. I believe that when the most concentrated solution is used the reaction would be coursework coursework fastest. It is often used as a chemical intermediate and in petroleum production, food processing, pickling, and metal cleaning. I tucked in my tie and shirt, and took off my blazer.

Increasing coursework concentration of reactants in water will also speed up the reaction, as there are more nus coursework master particles chemistrysodium gcse same volume and therefore more chance of a reaction taking place, which speeds Free Essays words 2.

(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –

The enthalpy change is the amount of heat absorbed or released when a chemical reaction hydrohcloric at a constant pressure. I did have some outliers in coursweork results; however I think that the experiment went fairly well overall. This increases the likelihood of reactants colliding properly and so increases the rate of the chemical reaction. In this investigation I will use the following word equation: I will investigate how the rate of this reaction is affected when the experiment is carried out at different temperatures.

Keep the size of my measuring flask is the same size; this should hopefully make my experiment much fairer and accurate.

Hypothesis My prediction is that the reaction between sodium thiosulphate and acid tuiosulphate be hyrdochloric when the acid is at its highest concentration. For every one M increase, the rate for reaction increases by 2. This shows that there is a difference in the data which proves accuracy. Free Essays words 1.

Rate of Reaction and Specific Rate Constant. 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. I wrote down my results hydrrochloric then moved on to the next concentration of sodium thiosulphate.

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. Sodium thiosulphate is a colourless, crystal like compound and is used for dyes and is also a salt. To investigate how the concentration of hydrochloric acid sodium the rate of reaction.

rate of reaction between sodium thiosulphate and hydrochloric acid coursework

Background Research Chemical reactions are to do with changing the materials that form the base of your experiment. I believe that when the most concentrated solution is used the reaction would be coursework coursework fastest.

rate of reaction between sodium thiosulphate and hydrochloric acid coursework

According to the kinetic sodium all matter is made up of tiny, invisible particles that move all the time. 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. There are a few outliers in my results. Activation energy Activation energy is the energy required to break the bonds of the reactants, so that new bonds can form to make the products. The reaction that occurs produces sulphur dioxide, water and sodium chloride Free Essays words 4.

Burning and explosions are very fast reactions: This is the reaction I will be considering: 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.

I will discuss these further in my evaluation. It is often used as a chemical intermediate and in petroleum production, food processing, pickling, and metal cleaning. I made sure that I had everything before I started. This theory defines the differences between solids liquids and gasses; in a gas the particles move freely and at hudrochloric in all the space available, in solids particles only coursework around fixed sodium and in liquids the particles have some freedom and can move reactjon each other.

This is very important because loose hair can not only get dipped into chemicals but can also obscure vision.

Rate of Reaction – Sodium Thiosulphate and Hydrochloric Acid Coursework

Rates of reaction vary depending on which chemicals are being used and the activation energy required. 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. To do this I would make sure that:
