Rates of Reaction Coursework. Introduction. In this piece of science coursework I will be experimenting how the rate of reaction between Sodium thiosulphate and hydrochloric acid is affected by the concentration of Sodium thiosulphate. I will measure the rate of reaction by mixing the different quantities of Sodium Practical: reaction between dilute hydrochloric acid and sodium thiosulphate solution ( GCSE Chemistry Coursework: Investigating the rate of a reaction. The Rate Of Reaction Between Sodium Thiosulphate and Hydrochloric Acid Anything that is highlighted in yellow is parts of the experiment in which we made - 7 min - Uploaded by Flinn Scientific Rate of Reaction of Sodium Thiosulfate and Hydrochloric Acid . pls do the experiment Rate of Reaction - Sodium Thiosulphate and Hydrochloric Acid Coursework The theory behind this experiment is that Increasing the concentration can increase is one of many that can be found in our GCSE Patterns of Behaviour section.
My coursework is based on rates of reaction. This deals with the time taken for reactants to be changed into products, when the variables are altered and analysed. Rates of reaction deals with the collision theory, this theory explains how frequently and how hard sufficient energy the reacting particles collide with each. Rates of reaction GCSE COURSEWORKCHEMISTRY2004AIMIn the experiment we use hydrochloric acid which reacts with the magnesium to form magnesium chloride. The hydrogen ions give hydrochloric acid its acidic properties, so that all solutions of hydrogen chloride and water have a sour taste; corrode active metals, forming metal chlorides and hydrogen; turn litmus red; neutralise alkalis; and react with salts of weak acids, forming chlorides and the weak acids. Magnesium, symbol Mg, silvery white metallic element that is relatively unreactive. In group 2 of the periodic table, magnesium is one of the alkaline earth metals. The rate of a chemical reaction is a measure of how fast the reaction takes place. It is important to remember that a rapid reaction is completed in a short period of time.
Category GCSE Chemistry Coursework Investigation; Title Rate of Reaction Between Marble Chips and Dilute Hydrochloric Acid First, you can start by describing the reaction situation you are intending to investigate. stirring of the reacting mixture size of reaction vessel volume of thiosulphate any added water to dilute etc. For example, with the word and symbol equation, short description about the reaction, and so on. If you are confident and chosen the VARIABLE you want to investigate you should try to make a quantative prediction and maybe justify it with some theory if you can. Example of the theory is the factors will increase the molecules inside the chemical and it will eventually increase the rate of reaction. You can continue in a broader context by introducing some background theory and descriptions of the factors or VARIABLES which may have an effect on the rate of the reaction you are studying (include briefly factors which might not apply). Is there any other factor for the reaction you are studying? In your 'method' description use the correct units or descriptors. will any of the reactants or products be affected by change in temperature or pressure? there are several reasons why the same acid should be used if its a reactant in the investigation, e.g. The factors to discuss might be: amount of limestone? (1) its the hydrogen ion, H (aq), is the active ingredient that actually 'attacks' the metal or carbonate, and acids can ionise to different extents, (2) 1 molar or 1 mol dm-3 (1M) H2SO4 is twice as acid as 1M HCl because each H2SO4 provides 2 H 's whereas each HCl just 1.
However, the second part of my prediction that for every increase of 10°C the rate of reaction is roughly halved, is only true in some places. For example, when the temperature is 40°C the reaction took 28.7 seconds and when the temperature was 50°C the reaction took 14 seconds which is roughly half the time. Introduction IGCSE COURSEWORK COORDINATED SCIENCE Name: Gabriel Tudela Teacher: Date: April 06, 2009 TITLE: Factors affecting the rate of reaction: Investigating the effect of concentration on the rate of reaction Skill(s) assessed: Topic C10 [Experiment 9 (in S4)] Investigating the factors affecting the rate of reaction IGCSE Coursework Skills C2, C3, & C4 Some of the factors affecting the rate of a reaction that you have studied are: * Temperature * Concentration * Surface area Aim: Investigating the effect of changing the concentration on the reaction between calcium carbonate and hydrochloric acid, by collecting the carbon dioxide gas given off. Ca CO3(s) 2HCl(aq) -- Ca Cl2(aq) H2O(l) CO2(g) Hypothesis: My hypothesis is that as we increase the concentration of the HCl, the rate of the reaction will be faster; this is because more collisions will be present Materials: - Small calcium carbonate chips - Dilute hydrochloric acid (1 moldm-3) ..more. Middle At the same time as you place the cork, start timing how much it takes to get 50cm3 of gas 10. Repeat this experiment using different concentrations of HCl acid by diluting the acid with distilled water, to make it a fair test use always the same amount of chips and always reach 25cm3 in the measuring cylinder so that only concentration and not amount will affect the rate of reaction 11. Record your results in a neat and tidy table Results: Table: Volume of 1.0 mol dm^-3 HCl (cm^3) Volume of H2O (cm^3) Concentration of HCl (mol dm^-3) Time (s) to reach 50ml Time to reach 100ml 5 20 0.2 38 133 10 15 0.4 17 35 15 10 0.6 9 18 20 5 0.8 7 13 25 0 1 5 10 Graph: Anomalous Results: In this experiment we were lucky to find no anomalous results at all, everything went on as we planned it was going to go like. Conclusion At this last 2 differences, at the change from 0.6 to 0.8, and 0.8 to 1 in mol dm^-3 of concentration of HCl, the difference was in both only of 2s, showing off that if the acid was yet too concentrated, and almost getting to being fully concentrated, the difference in time to reach the 50ml will become smaller and smaller.

Anjelina Qureshi Mrs Gravell Rates of Reaction Coursework Chemistry Year 11 Rates of reaction Introduction A chemical reaction occurs when things change from reactants Introduction This piece of coursework investigates rate of reaction. I will investigate how concentration of a solution affects the rate of reaction. I will be carrying out the experiment in which sodium thiosulphate solution (of different concentrations) is mixed with dilute hydrochloric acid. When these solutions are mixed and they react, a precipitate (meaning solid) of sulphur forms. The time taken for a certain amount of sulphur to form can indicate the rate of reaction. Once my two solutions are mixed I will use a stopwatch and record how much time it takes until I can no longer see a black cross beneath the beaker.

Libby Southwell 10d1 Chemistry Coursework Section 1 Brief Introduction We are carrying out an investigation to see whether the concentration affects the rate of Chemistry happens all around us, it governs who we are. As you understand it more, you can appreciate how much every bit of our lives depends on simple chemical processes - from the crude oil we use to make plastics to the composition of the air we inhale to keep alive. Chemistry can either be taken as a standalone GCSE or as part of a GCSE in Science - the latter often counts as the equivalent of two qualifications, with the course being made up of one third of each of Biology, Chemistry and Physics. The Chemistry GCSE aims to give students a basic background into the main principles of chemistry - acid/base reactions, calculations, industrial processes, chemical tests, hydrocarbons and chemistry in the environment. Topics included depend much upon the course and syllabus followed.
