Investigating a Neutralisation Reaction Between Hydrochloric Acid and Sodium Hydroxide

To investigate a neutralisation reaction I must know all the factors

that affect it in order to investigate in this.

Here are all the factors;

Temperature - This will defiantly affect an exothermic or endothermic


Concentration - If the solution is made more concentrated it means it

contains more particles of reactant, therefore more collisions are

likely and an result of this is that the temperature will decrease

because bonds are being made.

Type of Acid - Different acids all have different properties and can

cause different temperatures.

Type of Alkali - This is the same as the type of acid but instead the

different properties of an alkali.

Type of Reaction - Different type of reactions will either be

exothermic or endothermic. Example of this is a combustion reaction,

which is exothermic because of the heat it gives out.

These are the factors that will affect a neutralisation reaction. A

neutralisation is either exothermic or endothermic. Exothermic

reactions are the reactions that give out energy and therefore the

temperature rises as a result of this. Endothermic reactions are the

ones that take in energy from the surrounding and cause the

temperature to decrease as a result of this.

Making and breaking bonds either require energy or give out energy.

When breaking bonds it requires energy, which means it's a endothermic

reaction because the heat in the surrounding is absorbed to break the

chemical bond. When making bonds it gives out energy due to the

reaction that has been taken place and means that it's an exothermic


Every reaction that happens will either give out energy or take in

energy due to the type of reaction. The reason for this is because it

needs the energy or gives out the energy.

To tell weather it is an exothermic or endothermic reaction a

thermometer can be used to indicate what type of reaction it is. If

the temperature increases it means it is a exothermic reaction and if
