BACKGROUND INFORMATION What affects the rate of reaction? 1) The surface area of the magnesium. 2) The temperature of the reaction. 3) Concentration of the hydrochloric acid. 4) Presence of a catalyst. In the experiment we use hydrochloric acid which reacts with the magnesium to ...

The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the solution will become yellow and will change from...

How concentration affects reaction rate. The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the ...

Chemistry Coursework Rate of reaction Aim: Plan an investigation into the rate of reaction between Sodium thiosulphate and hydrochloric acid. Background information: • The equation for the rate of reaction is 1/time. • The rate of reaction measures the speed of reaction. It is ...

Introduction Rate of rate of hydrochloric acid and mangesium ribbon In the reaction between hydrochloric acid and magnesium ribbon, the hydrochloric acid will dissolve the magnesium and produce hydrogen gas. All chemical reactions involve reactants which when mixed may cause a chemical reaction...

Introduction In this investigation I am trying to find out whether or not the concentration of hydrochloric acid affects the rate of reaction. To do this we are going to make up different concentrations of hydrochloric acid starting with 100% and working our way to 20%. Prediction I predict th...
