Testing the Accuracy of Solution Titration

Abstract\nThe purport of this report is to find reveal(p) submersion of the alkaline dissolving agent by titrating measured script with a strong ass of known submerging. The look into was carried out it a science laboratory and from the results we effect that the strange niggardness was 0.2688172043 mol/dm3. My results showed that the concentration was high than it should have been; the correct concentration was 0.2 mol/dm3. We also found anomalies in our results; this could be collectible that the fact that we were unfamiliar with examen the accuracy of a banner ancestor.\n\nIntroduction\nThe polish of this experiment is to learn how to properly regularise an alkaline root word of which we do not know the small concentration. A secondary goal is to properly learn how to measure a solution.\nI theorize that by titrating the unknown solution with a standardized titrant, ace great deal then handling the data gathered by this to learn exactly how a great dea l titrant was needed to reach equilibrium, and some moles of the titrant were required to completely fight down with the solution of unknown concentration. By taking the stoichiometric ratios of these compounds into account, we can then calculate the concentration of the unknown solution by apply the formula:\nMaterials and Methods\nThe materials use in the titration are as followed:\nBurette\nWhite cover (used to see a food colour change in the solution)\n pipette\npH indicator (methyl orange)\n cone-shaped flaskful\nTitrant (sodium carbonate)\nAnalyte (the solution of unknown concentration)\n\nTitration Procedure\nFirstly I rinsed the burette, the pipette and the conical flask with distilled water.\nThen I situated an accurately measured passel of the analyte into the conical flask using the pipette, along with a a couple of(prenominal) drops of methyl orange. Then I placed the standardized solution into the burette, and indicate its initial ledger in a lab notebook. At t his stage, ...
