An Investigation Into the Rate of Reaction Between Hydrochloric Acid and Magnesium- Planning

Extracts from this document...

Introduction

AN INVESTIGATION INTO THE RATE OF REACTION BETWEEN HYDROCHLORIC ACID AND MAGNESIUM - PLANNING The aim of this investigation is to find out the effect of the rate in the reaction between hydrochloric acid (HCl(aq)) and magnesium (Mg(s)). Before beginning the experiment of finding out the effect of the rate of reaction between hydrochloric acid and magnesium, I will have to understand the meaning of rate of reaction and the factors that affect it. Collision Theory The rate of a chemical reaction is a measure of how fast the reaction takes place. A chemical reaction only occurs when particles collide (hit each other). The collision theory describes how the rate of reaction increases (the amount of hydrogen produced per second) when the concentration of hydrochloric acid increases. ...read more.

The minimum energy which is required in order for the particles to collide is called the activation energy. It is important to remember that a rapid reaction is completed in a short period of time. Some reactions are very fast e.g. an explosive. There are factors that may affect the rate of reaction, which are as follows: * Temperature. * Mass of a reactant. * Concentration of acid. * Surface area of a reactant. * Type of acid. All of these factors will change the rate of reaction because of the Collision Theory. Investigation In this investigation I will test different concentrations of hydrochloric acid reacting with magnesium. In the reaction between hydrochloric acid and magnesium ribbon, the hydrochloric acid will dissolve the magnesium and produce hydrogen gas. ...read more.

Conclusion

Na (Sodium) Li (Lithium) All too dangerous to react with a strong acid. Ca (Calcium) ...... Mg (Magnesium) Al (Aluminium) Manageable metals. These metals will react with hydrochloric acid as they are higher in the reactivity series than hydrogen and so a displacement reaction will take place. Zn (Zinc) Fe (Iron) ...... H (Hydrogen) ...... Cu (Copper) Pb (Lead) None of these metals will react with hydrochloric acid as they are all lower in the reactivity series than hydrogen, therefore a displacement reaction will not happen. Ag (Silver) Al (Gold) Depending on certain factors the rate that this reaction will take place will either increase or decrease. Question? My question is to see that if I change the concentration of the Hydrochloric acid for each experiment I will see an increase or decrease in the rate of reaction between Hydrochloric acid and Magnesium ribbon. ...read more.

    The time in which the magnesium ribbon disappeared via effervescence was determined visually. The error in judging when the magnesium had disappeared was larger that the error from the stop clock. As a result this error can be ignored. Another factor, which had to be kept constant, is the amount of surface area showing on the magnesium.

    I am using 0.005 moles of HCl, so the magnesium is 0.025/0.005 = 5 times in excess. This shows that at all times the magnesium is in a large excess. Observations When the magnesium was added to the hydrochloric acid in the boiling tube, the reaction mixture started to fizz:
