Neutralisation reaction essays

Neutralisation reaction essays In this coursework I aim to investigate whether changing the concentration of Hydrochloric acid and Distilled water will affect the reaction time in which it takes to dissolve an amount of magnesium strips. The experiment we have conducted as part of our GCSE Coursework is a neutralisation reaction. Before starting the investigation, I decided to do some research about magnesium and Hydrochloric acid. Magnesium is a light, shiny grey metallic element and its symbol in the periodic table is Mg. Magnesium is quite reactive when exposed to acid, and burns vigorously with a bright white light in air. Hydrochloric acid, HCl, is a solution of Hydrogen Chloride (a colourless gas) in water. The acid is a typical strong, monobasic acid forming only one series of salts, the chlorides. Like most acids it give of Hydrogen ions when it is added to water and certain metals. Below is a simple word equation to show how the reaction between Magnesium and Hydrochloric acid occurs. Before looking at all the factors that can alter the rate of the reaction, we must consider what happens when the reaction takes place. First of all, the particles of the reacting substance must collide with each other and, secondly, they need a certain amount of energy to break down the bonds of the particles to form new ones. If the collision between particles can produce sufficient energy (i.e. if they collide fast enough and in the right direction) a reaction will take place. The reaction however can be speeded up if the number of collisions is increased. ...
