PLANNING AIM: The rate of a reaction is the speed at which a reaction happens. If a reaction has a low rate, that means the molecules combine at a slower speed than a reaction with a high rate. Some reactions take hundreds, maybe even thousands of years while other can happen in less than one second. The rate of reaction depends on the type of molecules that are combining. In this investigation my aim is to investigate how the rate of a reaction is affected by changing the concentration of hydrochloric acid. I will be measuring how fast the reaction takes place by timing how long it takes for it to go cloudy. This is an indication that sulphur had been formed. Method: * Put all the equipment in the middle of the table. * Put goggles on. * Prepare the five different concentrations of HCI using the dilution table and a burette. * Use a measuring cylinder...
