Investigating the effect of varying concentration on the reaction betwe

Investigating the effect of vary concentration on the reaction between magnesium ribbon and hydrochloric sultryAimIt is to tell how the reaction between magnesium and hydrochloric sharp go out be effected if we diverseness the concentration of hydrochloric acid.IntroductionIn the try out the magnesium reacts with the hydrochloric acid tocreate magnesium chloride and hydrogen. The balanced cultivateula for thisisMg(s) + 2HCL(aq) MgCl2(aq) + H2(g) magnesium + hydrochloric acid Magnesium Chloride + HydrogenMagnesium exit react with hydrochloric acid, because it is higher(prenominal) inthe reactivity series than hydrogen. The magnesium displaces thehydrogen in the acid, so it forms magnesium chloride and hydrogen gas.Magnesium stripHydrochloric acid particlesThere are many variables that I can change, which are the temperatureand concentration of the hydrochloric acid, and the mass and the locate area of the magnesium strip. This is all true because they alllink to the do theor y of particles colliding with enough energyto make a reaction. It is based on the idea that for a chemicalreaction to take place, the reacting particles have to hit each(prenominal) otherhard enough to break or form new bonds. This is called a successfulcollision. When particles get stimulated or change magnitude in number, thereaction will increase in rate because fast-paced collisions will takeplace making more successful collisions.This plot line of battles five solutions hydrochloric acid and magnesium ribbon that are reacting. The arrows represent a simplified way to show how many successful collisions occur each second therefore the more arrows there are, the faster the rate of reaction. They show how different factors can affect the rate of reaction against t... ...at are really hard to keep constant soit would have been helpful to resort the experiment again or evenmore.The syringe could have stuck on the barrel just about it giving me lowerreadings on curtain point s or when the reaction stopped. I should haveput some lubricant around it to stop this from possibly happening.Further WorkI could test the concentrations for the ones in between worry 0.25 and0.75 to see how the rate of reaction changes. I could alike change theacid reactant to sulphuric acid or phosphoric acid to see and comparethe results with different molecular make-ups. The other reactant thatI could change is the type of metal I use. Using the less reactivemetals like zinc, aluminium, iron or lead enables me to test thehigher concentrations like 3M or 4M because the reaction will goslower so I will be able to read the results off the syringe properly.
