Chemistry planning and designing lab :: essays research papers

LabDate melodic theme The reactivity seriesProblem Which of the following coats are more labile with acids magnesium, zinc, aluminum, iron, lead, and copper?Hypothesis atomic number 13 is the closely reactive with acids because it occurs in congregation III.Aim To perform a comparative test on which metal is the most reactive with acids.Experiment A comparative test is do using time to find which metal has the fastest reaction cleverness P & DApparatus Equipment 1. 6 beakers2. Water3. Measuring piston chamber4. Watch or ClockMaterials 1. Aluminum foil2.Copper coin3.Lead pellets4.Zinc from a battery5. milligram from Antacid6. Iron ShavingsReagents 1. HClProcedure 1 launder the containers with distilled water.2. Pour 25cm3 of HCl in to each one beaker by use of measuring cylinder.3.Insert each of the contrasting sample metals into a beaker one at a time.4.Observe and track record the amount of time before the reaction stops with clock.5. Make a table of your observations .6. Setup a control using water as the reagent.Variables Independent Aluminum foil, Copper coin, lead pellets, Zinc from a battery,Magnesium from Antacid, and Iron Shavings.Dependent Reaction TimeControlled HClControl This is an identical try out using water as your reagent.Data The reaction time for the different metals , to show which is the most reactive in acids.MetalsReaction Time/seconds in acids.MagnesiumAluminumZincIronCopperPrediction Aluminum will be the most reactive because it is in group 3 which has the least amount of electrons to loose.Results The results for reaction time of the different metals, to show which is the most reactive in acids.
