To show how concentration can affect the speed of a reaction.

Extracts from this document...

Introduction

Title: Chemistry Investigation AIM: To show how concentration can affect the speed of a reaction. Investigate how concentration different the reaction between sodium thiosulphate and hydrochloric acid. If a burning splint is put near a balloon full of hydrogen, there is a very loud bang. A chemical reaction has happened. Hydrogen has burned in air to make water vapour. The reaction happens very fast indeed. When a cake is being cooked in the oven, a series of chemical reactions are happening. They happen only slowly -it may take 30 minutes or more to cook the cake. All the time an apple is ripening on a tree, chemical reactions are happening. ...read more.

Middle

As the reaction happens, carbon dioxide gas is produced. There are two possible ways to measure how fast the reaction is happening. I would be starting the prediction to see the chemical reaction that is going to be taking place. As the reaction take place the oxygen started to be produce. This is because the temperature will increase and when it does the reaction will speed up. Increasing the concentration of reactants increases the rate of a reaction. This is because there are more particles in the same volume so more collisions are possible every second. Factors affecting the rate of a reaction: Increased temperature will make the reaction go faster. When you increase the temperature the particles will collide more effectives collision. ...read more.

Conclusion

To make this experiment safe I would be using gurgle to make shore it does not get in contact with the eye. I would also be using dilute hydrochloric acid so if it spilt on you there would be no hazard. I will collect the equipment conical flask, stopcock, sodium, measuring cylinder, , and gas syringes. I will measure thiosuphate into a conical flask using 100M measuring cylinder. I will Measure 5M of hydrochloric acid using 10M measuring cylinder. Draw a cross on a piece of paper place the conical flask on it. Take temperature using the monometer mix together and start the clock. My investigation have prove that there is a chemical reaction and it has taking place during the experiment. ?? ?? ?? ?? SYLVANUS JENKINS 11N3 ...read more.
