Experiment to investigate factors affecting the compute of reaction amid magnesium medal and hydrochloric acidRates of Reaction investigatingExperiment to investigate factors affecting the rate of reactionbetween magnesium ribbon and hydrochloric acid.Chemical reactions between substances are ca utilised by the collision ofparticles. more collisions mean a quicker rate of reaction.In the reaction between hydrochloric acid and magnesium ribbon, thechemical reaction takes place when the magnesium ribbon is droppedinto the hydrochloric acid. The products are hydrogen gas andmagnesium chloride.The equation for this reaction is as follows-Magnesium + Hydrochloric acid Magnesium chloride + HydrogenMg (s) + 2HCL (aq) MgCl2 (aq) + H2 (g)Factors that affect the rate of reaction-* Temperature* Mass of magnesium ribbon* Concentration of hydrochloric acid* rise up area of magnesium ribbonI have chosen to use the concentration of hydrochloric acid as myindependent variable. These differe nt concentrations can be variedeasily and made up accurately for the taste.Each experiment will be done four times so that an bonnie reading canbe calculated - ensuring an accurate and reliable conclusion. The calculated variable will be the time taken for the same measurement ofmagnesium ribbon in each experiment to be use up in reaction. Theconstant variable will be the space of the magnesium ribbon used ineach experiment.Rate of reaction = Gradient of the line of a graph plotted with timetaken to cease reacting againstconcentration.Concentration of a solution describes the number of active particlesin a particular volume.The unit of concentration is mol.dm-3PredictionI assure that the higher the concentra... ...ing aroundfaster. This would mean HCL and magnesium particles would collide morefrequently, thereby increasing rate of reaction.I think that my results on graph 1 were suitable to draw an accuratebest-fit line. The points are all joined by the line.I used 5 differen t concentrations which were in a fitly wide range.If I were to repeat the experiment I would use a slightly wider rangeof concentrations to expand my conclusion, such as 1.25M, 0.75M and0.25M. If the resources were available, I would to a fault extend the rangeto higher concentrations than the 2M I was restricted to in thisinvestigation. set ahead investigation could also include using another factor as myindependent variable.I could differ the surface area of magnesium in my experiments, andsee how this affects rate of reaction in what way and if there is adefinite proportional relationship.
