How does the amount of acid reacted with an alkaline affect how much energy is transferred as heat?
Method
List of equipment used
Thermometer- to measure how much energy has been transferred as heat during the different reactions.
Goggles- To protect our eyes from the acids and alkaline we’re using. Risk assessment
Before starting our experiment we need to take a few precautions to make sure our experiment won’t cause harm to anyone, and to make sure we know what to do in the event of an accident occurring.
If an acid or alkaline is spilt make sure it is cleaned up immediately with paper towels and water since spilling these liquids on the floor could result in someone in the lab slipping, which could cause a serious injury such as hitting their head on the floor or work benches and damaging one of their limbs or the acid or alkaline could come in contact with the someone’s skin.
Also acids and alkaline are corrosive and so are immediately dangerous to the tissues they contact, since they can damage living tissue so if they come into contact with someone’s skin wash it off immediately with water or if it’s serious enough to have caused chemical burns see the school nurse.
Goggles should be worn at all times to prevent an acid or alkali getting into the eye however if this does happen immediately wash your eye out with cold water and then visit the school nurse.
If any beakers/flasks/test tubes are dropped they should be picked up off the floor straight away to prevent someone from tripping over it and causing harm to themselves. Also if the beakers/flasks/test tubes are smashed a dust pan and brush should be obtained and all the fragments of glass should be put into the bin. The teacher should also be warned since smaller pieces of glass may have been missed and cause harm to someone by penetrating their skin.
While doing the experiment always make sure all bags are underneath the table so no one can trip on them and that all stools are underneath the table. Never sit on a stool while doing an experiment since if something goes wrong during an experiment such as something dangerous like the acid spilling everywhere it’s harder for the person doing the experiment to quickly get away from the danger while sitting on a stool, so all experiments should be done standing up.
Also while doing an experiment make sure that people with long hair tie their hair up so it doesn’t affect the experiment, and people with ties hanging loosely should tuck them in or take them off. For example of hair or someone’s tie gets into an acid or alkali it could affect the person’s experiment and potentially cause danger to them.

Background research
Exothermic reaction-
An exothermic reaction is a reaction that releases energy in the form of light or heat. It is the opposite of an endothermic reaction. An exothermic reaction is a chemical or physical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released. reactants → products + energy
Endothermic reaction-
Chemical endothermic reactions need heat to be performed. In a thermochemical reaction that is endothermic, the heat is placed on the reactants' side (heat is necessary for and absorbed during the reaction). The heat absorbed during the chemical reaction results in a decrease in temperature of its surroundings. This principle is employed in instant cold compresses (ice packs) which are used in first-aid.
Neutralisation reaction-
A chemical reaction happens if you mix together an acid and a base. The reaction is called neutralisation, and a neutral solution is made if you add just the right amount of acid and base together. A salt is any compound which can be derived from the neutralization of an acid and a base. The word "neutralization" is used because the acid and base properties of H+ and OH- are destroyed or neutralized. In the reaction, H+ and OH-
