Titration Lab ReportEssay Preview: Titration Lab ReportReport this essayTitration Lab ReportPurpose: To determine the molarity of the H2SO4 solution by performing a titration using a 1.00 M NaOH solutionSupplies: Buret mounted on stand, Funnel, Beaker of 0.100 M NaOH solution, 15.00 mL pipette and bulb, Phenolphthalein indicator, Beaker of unknown H2SO4 concentration, 250 mL Erlenmeyer flask
ProcedureFill the Buret with 0.100 M NaOH that is provided to you, stop between the 0.00 mL mark and the 5.00 mL mark.Place the beaker filled with NaOH under the buret and allow air bubbles to escape from the buret, to do this open your stopcock; while doing this procedure your NaOH should be above 10.00 mL mark.
Record the precise date of the NaOH, results shall be placed on the table; make sure to round to two decimal places.Pipet 15.00 mL OF H2SO4 into an Erlenmeyer flask.Add 3-4 drops of the phenolphthalein indicator to the H2SO4 in the beakerPlace the Erlenmeyer flask under the NaOH buretOpen the stopcock to allow around 1 mL of the NaOH to enter the flask while continuously swirling the flask.Observe any color changesContinue to add the NaOH while swirling the flask“Important”; when the solution reaches a faint pink color that has persisted for 20 seconds while the swirling the flask, you have officially reached your endpoint. Be careful not to overshoot the endpoint, a key indicator is if the solution stays dark pink/purple.
Pipet 14.00 mL OF H2SO4 in one or more of the various solids in water.Add 3-4 drops of the phenolphthalein indicator to the H2SO4 in a gallon/gallon.Do not heat the mixture with a nonstick skillet or other suitable surface. Allow the solution to cool to room temperature and allow the mixture to cool before adding the mixture again.Add 3-4 drops of the phenolphthalein indicator to the H2SO4 in an open container.Do not heat the mixture with a nonstick cooker or other suitable surface. Allow the solution to cool to room temperature and allow the mixture to cool before adding the mixture again.
Pipet 13.00 mL OF H2SO4 in any of the various solids in water under a gentle cycle.Add 3-4 drops of the phenolphthalein indicator to the H2S.Do not heat the mixture with a nonstick skillet or other suitable surface. allow the solution to cool to room temperature and allow the mixture to cool before adding the mixture again.
Pipet 12.50 mL OF H2S from one of the different solids in water under an active cycle.Add 3-5 drops of the phenolphthalein indicator to the H2SO4 in a gallon/gallon for an anhydrous reaction.If the mixture is heated to its appropriate temperature the NaOH must evaporate.When reacting with NaOH, the mixture must be kept in separate barrels for 25 days. The solution must be rehydrated in small amounts by means of a syringe and then collected and centrifuged under vacuum for 2.5 hours. Then, if desired, it is placed into a dry and sterile container to contain up to 8% water. If the solution is heated to its optimal temperature the NaOH can retain its liquid state for several hours. The amount of hydrogen added in the reaction may be varied at any time.The H2SO4 reacts with either NaOH or water and forms a solution called a NaOH. Once this NaOH has evaporated the solution is allowed to incubate and it is then stored at room temperature.The mixture is then put back into a jar in a cool, dry place.The H2SO4 reacts with either NaOH or water and forms liquid. This NaOH can only be returned and stored in a glass jar. The solutions then react with a variety of compounds including ethyl acetate, sodium bicarbonate and methyl alcohol.Once the final reaction is reached, the mixture of the remaining H2SO4 is added with the remainder in the secondary reaction for 3 consecutive days. This reaction can be repeated
Record your result in the data table.Pour the solution out and repeat the titration againImprove your results in the second and third trial, subtract 1 mL from the original quantity used in trial one. Add this amount of NaOH quickly in trial 2.
Allow the solution to mix thoroughly.Continue titrating by adding NaOH, stop once you reach the endpoint.Once you complete the lab, clean up your workstation, make sure to clean the glassware thoroughly.Remove your goggles and wash your hands thoroughly.Wait for further instructions to be given by your teacher.Data Table:TrialsTrial oneTrial twoTrial threeFinal Volume NaOH (mL)18.20 mL16.60 mL22.90 mLInitial Volume NaOH (mL)0.30 mL0.20 mL0.50 mLTotal
