Problems can also arise in the sampling process. According to Purdue University, "A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution." SOURCE : Titration, as you already know, is a very precise procedure in measuring the volume of liquids. The calibration of the balances is periodically checked using a registered balance used in a titration experiment are technically sources of systematic error, these errors are easily avoided. This can be minimized by having a large excess of iodide in order to keep the iodine tied up as tri-iodide ion. Sampling Errors. It can be either of end point error, misreading volumes, concentrations, faulty … There are plethora of sources of errors to occur in due course of titration. NaOH is a base which can vary the results because it is hydroscopic, not using a hydroscopic base … Several factors can cause errors in calibration results, including misreading volumes, faulty concentration values, or a wrong technique. It should also be apparent that the titrations involving iodine must be made in cold solutions in order to minimize Potassium permanganate solutions are not stable and they should be filtered and normalized every 2-3 months. Loss of iodine by evaporation from the solution. There are a large number of sources of errors occurring in time of calibration. 1.) The solution of the known concentration is introduced into a specific volume of the unknown through a burette or pipette. sources of errors. There are plethora of sources of errors to occur in due course of titration. Sources of errors in titration Titration is a quite sensitive analytical method that lets us determine an unknown concentration of a chemical in solution by introducing a known concentration of another chemical. Titration: A titration is a volumetric analytical technique used to measure the amount of volume added to an unknown sample. However, since it is so sensitive and accurate a lot can occur throughout the procedure to give erroneous results. It can be either of end point error, misreading volumes, concentrations, faulty use of equipment, contaminated glass ware, etc. It can be either wrong endpoint, wrong reading sizes, concentrations, faulty use of equipment, contaminated glass panels, etc. I’m sure you’ve learned at some point that the pH value of the titration endpoint depends on the acid dissociation constant (K a) of the acid and base that are used.If a strong base is titrated by a strong acid, the pH value at the endpoint is around 7. To get the most accurate results, chemists must either take samples from a large population size or obtain multiple samples from the population size selected. Apart from general sources of titration errors, when titrating hydrogen peroxide we should pay special attention to titrant. Several factors can cause errors in titration findings, including misreading volumes, mistaken concentration values or faulty technique. Care must be taken as the solution of the known concentration is introduced into a specific volume of the unknown through laboratory glassware such as a burette or pipette. Choosing the right indicator. Sources of error/uncertainties: If the tablet is squashed into powder some of it stays in the paper or the powder may also stick to the walls of the beaker when poured.
