Experiment to investigate factors pushing the rate of reaction between magnesium ornament and hydrochloric acidRates of Reaction InvestigationExperiment to investigate factors affecting the rate of reactionbetween magnesium ribbon and hydrochloric acid.Chemical reactions between substances ar caexercisingd by the collision ofparticles. More collisions mean a quicker rate of reaction.In the reaction between hydrochloric acid and magnesium ribbon, thechemical reaction takes erupt 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* Surface area of magnesium ribbonI have chosen to use the concentration of hydrochloric acid as myindependent variable. These different concentrations can be variedeasily and made up accurately for the experiment.Each experiment go out be done four times so that an average reading canbe calculated - ensuring an accurate and reliable conclusion. Themeasured variable exit be the time taken for the same quantity ofmagnesium ribbon in each experiment to be used up in reaction. The invariable variable will be the length of the magnesium ribbon used ineach experiment.Rate of reaction = Gradient of the line of a graphical record 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-3 portentI predict 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 different concentrations which were in a suitably 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 also deport the rangeto higher concentrations than the 2M I was restricted to in thisinvestigation.Further 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.
