Investigating how Concentration Affects the Rate of Reaction Between Magnesium Ribbon and Hydrochloric Acid Aim: We intend to look at the different factors that affect the rate of reaction between hydrochloric acid and magnesium ribbon. This variable will affect the time it takes for the two substances react, depending on a variation of the factor. Some of these factors are: * Surface Area * Temperature * Catalysts * Concentration * Pressure * Stirring / Mixing However, some of these variables cannot be tested easily or accurately, so only one variable will be chosen. The variable I have chosen is concentration, using up to 3 molar hydrochloric acid. Background Information Here is some information on how * Surface Area - If you increase the surface area of the substance you are trying to react with another then there are more available molecules to collide with the other substance's molecules. This increases the rate of reaction. * Temperature - For a reaction to take...
