Accuracy Of Measuring Instruments For Titration in Nagpur

People who conduct a titration experiment believe that their results are as accurate as possible. But, like any other experiment, the titration experiments contain limitations. The aim of a titration experiment is to figure out the accurate measurement of a particular quality in an unknown solution. This is done by gradually adding little quantity of a known solution to the unknown solution until a chemical reaction takes place. A very common example of a titration experiment involves the addition of an acidic solution slowly to an alkaline solution until the pH is neutralized completely.

Determining The End Point For Titration in Nagpur

The most obvious and common titration experiment limitation is that the end point of the process do not necessarily equals the equivalence point precisely. When we look at the titration curve, it illustrates that when the equivalence point is reached by the solution, the measured variable drops incredibly quickly. This makes it difficult to find out the exact equivalence point. Finding out the equivalence point becomes difficult in some cases. This is because the color changes representing the end point only occurs after the quantity of titrant has exceeded the quantity of the analyte.

Accuracy Of The Measuring Instruments

The pipettes and burettes are the glasswares used to measure the solutions. These glasswares can also act as limitations in titration experiments. Glasswares can be calibrated but these calibrations are not completely accurate always. The structure of burette is complex. This adds another limitation i.e. the possible existence of an air lock into the burette’s stopcock. This can interrupt the flow of added solution, leading to inaccurate results.

Human Errors

The human errors pose many limitations to a titration experiment. For instance, if a sample solution is left open, there is a possibility that a small quantity of the solution may have evaporated. The analyte could be contaminated if between measuring the analyte and the titrate, the pipette was not washed with distilled water. Conversely, if between measuring the two solutions the pipette was washed, a small quantity of distilled water could remain. This will dilute the analyte slightly. Interpreting a color scale inaccurately or using smudged glassware can also affect the titration experiment.
