Chemistry Coursework 1 Aim: To find the effects of the concentration of hydrochloric acid on the rate of reaction on marble chips. Introduction: The concentration of acid in a solution is dependant on how many particles there are of the acid in it. As you increase the concentration of the acid, there will be more acid particles in the same volume. For example, if you use the same tap water and pour it into a 100ml beaker and a 1-litre beaker the concentration would be the same. Only if more particles of water are added will the concentration rise. Marble chips can dissolve in acids; if the concentration of the acid is varied then the speed of the reaction will either slow down or speed up. All substances are made out up of particles, before we can get a chemical reaction the particles of the two substances must collide against each...
