Nobody in my group was asthmatic but if they were, I would have carried out the experiment near a window or in a fume cupboard. Iodometric Determination of Cu in Brass In acid solution practically all oxidizing agents will oxidize iodide ion to iodine quantitatively. As I was using liquids, I had to consider concentration and temperature of the liquids. The peak is at a higher energy. It is the final change that results increase in rate, even with a relatively small increase in temperature.

A pair of goggles will be worn during the heating part of the experiment in order to protect the eyes. 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. If the students are going to investigate temperature they will need three water baths and a range of temperatures. 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. Using white paper helped the marking to stand out. Rates Of reaction- The reaction between limestone and hydrochloric acid words – 3 pages AimDuring this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. As the hydrochloric acid mixes with the sodium thiosulphate and the water in the flask, the stopwatch is started.

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

I measured the gas produced from the reaction every minute for five minutes. We did 4 experiments to find out how the rate of reaction changes with differing concentrations of Sodium Thiosulphate, Hydrochloric Acid and water.

Aacid drew 6 different graphs for this investigation.

I tucked in my tie and shirt, and took off my blazer. As I was using liquids, I had to consider concentration and temperature of the liquids. Menu Factors that influence sources of financing Travel tours business plan sample Write a letter to your head teachers quiz. One typical reaction to explore at secondary level is the rate of the reaction between magnesium ribbon and hydrochloric acid.

sodium thiosulphate and hydrochloric acid coursework conclusion

In this investigation the rate at which aluminum replaces hydrogen from a solution of hydrochloric acid will be observed. 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 equation for this reaction is: 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 peak is at a higher energy. They react as in the equation below: Coursework about sodium thiosulphate and hydrochloric acid.

And supports my conclusion. There are a few outliers in my results. When a chemical reaction takes place the particles of the reactants collide. This shows that there is a difference in the data which proves accuracy. How the rate of reaction changes in a reaction between Hydrochloric Acid and Sodium Hydfochloric words – 4 pages Chemistry coursework: In my scatter graph with line of best fit, most of the points are close to the line.

Help Center Find new research papers in: If the students are going to investigate temperature they will need three water baths and a range of temperatures. Use of rate of sodiumm 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.

The theory behind this experiment is that ‘Increasing the concentration can increase the rate of the reaction by increasing the rate of molecular collisions.

In the case of liquid solutions, the concentration of the elements is also important when considering whether the reaction will be successful or not. PlanningWhat I going to investigate is how different factors affect the rate of the chemical reaction of Sodium Thiosulphate and Hydrochloric acid.

As soon as the chemicals were in, I started the timer.

Technological development in india essay ckursework reviews recommendations thesis pointers dissertation on anorexia nervosa examples of college essays extracurricular activities. Iodometric Determination of Cu in Brass In acid solution practically all oxidizing agents will oxidize iodide ion to iodine quantitatively.

Rates of reaction vary depending on which chemicals are being used and the activation energy required. Sodium thiosulphate solution is standardized against potassium dichromate in presence of hydrochloric acid and potassium iodide. In our experiment, we are reacting it with sodium thiosulphate. hydroclhoric

The rate of reaction is the rate of loss of a reactant or the rate of development of a product during a chemical reaction.
