# Investigating the rate of reaction between magnesium and hydrochloric acid.

Extracts from this document...

Introduction

Investigating the rate of reaction between magnesium and hydrochloric acid Aim In this experiment I aim to investigate the rate of reaction between magnesium and hydrochloric acid. This reaction rate will be affected by different variables, which can be changed; these are Temperature of the hydrochloric acid, mass of magnesium and concentration of the hydrochloric acid. Others things can effect the reaction rate but these are the main variables. In this experiment I will only alter one of the variables and keep the rest at a constant rate. For this experiment I will concentrate on the concentration of the hydrochloric acid and see what the effects are on the rate of reaction when this is altered. Prediction I predict that the higher the concentration of the acid the quicker the reaction time I no this because, "rate plus concentration are directly related" (Salter's A-level chemistry second edition chapter 10). This tells me that the concentration will directly affect the rate of reaction. To back this prediction up I have to look at the collision theory, this states that for the two different reactants to react the particles ...read more.

In experiment A the reaction is over after 60 seconds this was doubled in experiment B proving my theory that when the concentration is doubled the reaction time is also doubled. The theory also follows the same rule for average rate, as in experiment A the average rate per second is 1cm3 where as the rate for experiment B Is 0.5cm3. For each experiments 60cm3 of hydrogen was produced. Method To carry out this experiment I will need the following apparatus; * Safety goggles * Thermometer (to keep a constant temperature so that the experiment is not effected by it, and will not change the reaction time) * Measuring cylinder (to measure the amount of hydrochloric acid and water) * Conical flask (to hold the water and hydrochloric acid in while the experiment is taking place.) * Syringe (to measure the amount of gas let off and also to tell when the reaction is complete) * Cork and tube attaching the conical flask and syringe together (to allow all the gas to travel into the syringe) ...read more.

to react a chosen length of magnesium ribbon with a chosen volume of hydrochloric acid. I will measure the rate of reaction by timing how long a magnesium strip will react with different concentrations of hydrochloric acid. I only require three results as I am going to measure the average speed of reaction for each concentration of hydrochloric acid.

1. ## What effects the rate of a reaction

Hydrochloric Acid is made up from Hydrogen chloride. Hydrogen chloride is a colourless gas with a pungent, choking smell. It gives steamy fumes in moist air and is very soluble in water, forming Hydrochloric Acid. This is a strong acid. Hydrochloric acid is easily oxidised by such compounds as Manganese Oxide.
