Investigating how changing an acid concentration Changes reaction rate Aim: To find out how increasing the concentration of acid changes the speed of a reaction. Reaction Used: Magnesium + Hydrochloric acid - Hydrogen + magnesium chloride. Mg + 2HCL - NgCL2 + H2 Prediction: As the acid gets stronger, the reaction will go faster. This is because in a stronger acid, there are more particles of acid which collide into the magnesium ribbon. In a weaker acid, you wont get as many acid particles per litre, so there will be less collisions with the magnesium ribbon. Equipment and Reagents: 4 concentrations of Hydrochloric acid - 0.5 m 1.0 m 1.5 m 2.0 m Strips of 3cm magnesium ribbon Ruler Scissors Beaker Goggles Pippet Funnel Fair testing: There are two different factors to the fair testing of this experiment, they are what we Will Control and what Will Vary. Will Control: We will control the following things - Size of the magnesium strip - The temperature of the acid - The movement -...
