Iodometric titration is better than iodimetric titration for the determination of reducing agents, as it directly measures the amount of oxidizing agent present. This method is more precise, as it involves the direct reduction of a known quantity of iodine to iodide ion. It is also less prone to interference from side reactions compared to the indirect measurement in iodimetric titration.

Why is GC MS better than titration?
Using GC MS (Gas Chromatography Mass Spectrometry) you may detect multiple substances within a sample and in very trace amounts. Titration will tell you the concentration of a solution, and is more subject to error.
Why is Volume of HCl used for blank titration is more than volume of HCl used for oil titration?
The blank titration is used to determine the exact amount of acid needed to neutralize any impurities in the titration setup, such as the indicator and solvent. This additional volume of acid is accounted for in the blank titration and is subtracted from the volume of acid used in the titration with the oil sample.
Why is GC-MS better than titration?
Using GC MS (Gas Chromatography Mass Spectrometry) you may detect multiple substances within a sample and in very trace amounts. Titration will tell you the concentration of a solution, and is more subject to error. You can measure the quantity of the stuff you're looking for much more exactly with GC-MS. Also, you can detect several sorts of molecules at once, whereas you need a pure probe for titration.
Can you use indicator other than phenolphthalein in the titration of NaOH?
Yes, you can use indicators such as bromothymol blue or methyl orange in the titration of NaOH. These indicators change color at different pH ranges and can be used based on the specific pH endpoint needed for the titration.
Why potentiometric titration instead of direct titration?
Potentiometric titrations are based on standard electrode potential change observed through potentiometer. But direct titrations are based on physical observation on color change by a human. In other words the detection of the endpoint can be noted from significant change in the voltage or millivoltage value in the case of potentiometric titration. So both precision and accuracy can be achieved in potentiometric titration.But in the case of direct titration using an indicator, change in the color is the criteria and the observation of color change can vary from one person to other and so both precision as well as accuracy cannot be achieved. For instance in an acid-base titration using methyl orange indicator, the color change observation is significantly vary from person to person.Moreover in potentiometric titration the equivalence point (different from end point and equivalence point is more accurate than end point) can be noted from a second derivative graph. So pinpoint accuracy over the titration results can be accomplished in a potentiometric titration.ByDr M Kanagasabapathy PhDAsst.

Why is it better to use white vinegar rather than balsamic or apple cider vinegar for the titration?
White vinegar is better for titration because it has a consistent and predictable acetic acid concentration, typically around 5%, making it easier to obtain accurate measurements. In contrast, balsamic and apple cider vinegars can have varying acidity levels and additional flavor compounds that may interfere with the titration process. This consistency in white vinegar allows for more reliable calculations of concentration and pH.

How do the characteristic of bases differ form those of acids?
Bases tend to recieve an H+ ion in a titration, and acids tend to give an H+ ion in a titration. Bases have a pH greater than 7 and acids have a pH less than 7.

Why starch is added in iodometric titration?
Starch is added in iodometric titration as an indicator to detect the endpoint of the titration. In the presence of iodine, starch forms a blue complex that is easily visible. The appearance of this blue color signifies that all the iodine has reacted with the analyte, helping the person conducting the titration to know when the reaction is complete.
What happens if the tip of the burette is not filled before the titration begins?
If the tip of the burette is not filled before the titration begins, inaccurate volume readings may result due to the introduction of air bubbles into the liquid being dispensed. This can lead to imprecise titration results and affect the accuracy of the experiment.
Why is phenolphthalein indicator not used in EDTA titration?
Phenolphthalein is not suitable for use in EDTA titration because it changes color at a pH range that is much lower than the pH range at which the EDTA-metal complex formation occurs. EDTA titration typically requires indicators that change color in a more acidic pH range.
What is the difference between aqueous and non aqueous titration?
Aqueous titration involves using a water-based solvent for both the titrant and the analyte, while non-aqueous titration involves using a solvent other than water. Aqueous titrations are more common and are used for analyzing compounds that are soluble in water, while non-aqueous titrations are used when water may interfere with the reaction or when the compounds are not soluble in water.
