Testing the Accuracy of Solution Titration

Abstract\nThe purpose of this enunciate is to find out assiduousness of the alkalic firmness by titrating measured volume with a strong base of cognise concentration. The experiment was carried out it a science lab and from the results we base that the occult concentration was 0.2688172043 breakwater/dm3. My results showed that the concentration was higher than it should fetch been; the correct concentration was 0.2 groyne/dm3. We also found anomalies in our results; this could be due that the position that we were unfamiliar with testing the accuracy of a standard solution.\n\n demonstration\nThe goal of this experiment is to check over how to aright standardize an alkaline solution of which we do non know the exact concentration. A secondary goal is to properly win how to titrate a solution.\nI hypothesize that by titrating the unknown solution with a standardized titrant, one sack wherefore use the info gathered by this to learn exactly how much titrant was ind ispensable to reach equilibrium, and many moles of the titrant were needful to completely react with the solution of unknown concentration. By pickings 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 used in the titration are as followed:\n buret\nWhite tile (used to date a colour channelize in the solution)\nPipette\npH indicator ( methyl radical orange)\nConical flaskful\nTitrant (sodium carbonate)\nAnalyte (the solution of unknown concentration)\n\nTitration act\nFirstly I rinsed the burette, the pipet and the conical flask with distilled water.\n then(prenominal) I rigid an accurately measured volume of the analyte into the conical flask using the pipette, on with a few drops of methyl orange. Then I placed the standardized solution into the burette, and forecast its initial volume in a lab notebook. At this stage, ...
