Nazreen Deller Chemistry Coursework 12/10/02 Aim : An investigation into the variables that effect energy changes during a neutralisation reaction. Background information : A neutralisation reaction is a process whereby the acidity or alkalinity of a substance is destroyed. In order to make a neutral substance you must first determine the ph of the substance, one you have determined whether it is alkali or acid you can then add the same mount of alkali if the substance is acid. This will remove H+ (aq) ions. If the substance is an alkali then you must add the same amount of acid, removing the OH- (aq) ions. It is important that the acid and alkali particles are exactly equal to get a neutral solution. When two chemicals are neutralised, a reaction occurs. This reaction normally results in an event called 'energy change'. An energy change is normally the discharge of energy lost in a reaction....
