What else can I help you with?
What will happen to the molarity of NaOH If a drop of NaOH falls out of the flask during the titration?
You have to realise that a drop from the burette for instance is insignificant, if you are dealing with at least 10ml solution which you usually deal with on a titration. If you don't want to regard it as insignificant, then if NaOH is in the burette, then the solution doesn't become more concentrated with NaOH because that drop escaped.
What instrument is used in measuring?
Titration involves the use of a buret and also an Erlenmeyer flask or beaker (where it is measured).
Why do you titrate into a flask and not a beaker?
Flasks have a more narrow neck, which reduces the risk of splashing or spilling the titrant during the titration process. This allows for more precise control of the titration endpoint and accurate measurements. Beakers have a wider opening, making them less suitable for precise measurements and control of the titration.
Why is that when NaOH H2SO4 and phenophtalein in conical flask becomes hot after shaking during titration?
The reaction between NaOH and H2SO4 is highly exothermic, meaning it releases heat. When the solutions are mixed in the conical flask and shaken during titration, this reaction occurs and produces a significant amount of heat. Additionally, the presence of phenolphthalein might contribute to the sensation of heat as it can change color when exposed to heat or pH changes, indicating the progress of the reaction.
Could a 25 ml volumetric flask be replaced by a 25 ml pipette to measure the solution poured into a conical flask for titration?
As the pipette is far more accurate than a flask by a factor 10 to 100 one should NOT use a volumetric flask except for standard volumes over 100 ml.
Why was the conical flask not washed with the alkali solution it was going to contain during titration?
So that no extra moles of NaOH were present in the flask.
Why the walls of the flask are washed with distilled water during titration?
Washing the walls of the flask with distilled water during titration helps ensure all of the solution in the flask participates in the reaction. It removes any residual solute that may be stuck to the walls, preventing errors in the titration results. Additionally, it helps in maintaining the accuracy and precision of the titration by preventing contamination from previous reactions.
Why you rinse titration flask with water?
Rinsing the titration flask with water is done to ensure that all of the titrant (the solution being titrated) is transferred into the flask for accurate measurements. By rinsing, you can be sure that no titrant is left behind on the walls of the flask, ensuring a complete reaction during the titration process.
Why does it not matter if conical flask you wet with water during titration?
Wetting the conical flask with water during titration helps to ensure thorough mixing and prevents solution splashing or clumping on the sides of the flask. This can help in obtaining accurate and consistent titration results.
Why the walls of the flask are washed with de-ionised water during titration.how does this affect the outcomes of the titration?
The walls of the flask are washed with de-ionised water to ensure that all the solute from the walls is transferred into the solution being titrated. This ensures that the titration results are accurate and precise, as any solute left on the walls could skew the results by affecting the concentration of the solution being titrated.
What is the name of solution taken in the flask during titration?
The solution taken in the flask during titration is called the "analyte" solution. It is the solution being analyzed and measured for its concentration or reacting with a standardized solution.
Why the titration flask need to be shake during titration?
Shaking the titration flask during titration helps to ensure that the reaction mixture is well-mixed and that the titrant is evenly distributed throughout the solution. This promotes a more uniform reaction and more accurate measurement of the endpoint of the titration.
What is the titration flask?
A titration flask is a glass vessel with a narrow neck and a flat bottom used in titration experiments. It typically has volume markings for precise measurement of liquids added or titrated during the experiment.
What is titration flask used for?
A titration flask is used in the laboratory to hold and contain the solution being titrated. It typically has a narrow neck and a stopcock at the bottom to control the release of the titrant into the reaction mixture during the titration process.
Which solution in the titration is taken in conical flask?
The solution being titrated is placed in the conical flask. The titrant (the solution being added during titration) is then slowly added to the solution in the conical flask until the endpoint is reached.
Why does adding distilled water in the conical flask during titration not affect the titration result?
Adding distilled water in the conical flask during titration does not affect the titration result because the volume of the solution in the conical flask affects the concentration of the titrant solution. As long as the same volume of titrant is delivered from the burette and reacts with the analyte, the concentration of the titrant and the volume of the analyte solution will remain the same, ensuring accurate results.
What happens to a pH of a solutionin a conical flask during a titration?
During a titration, the pH of the solution in the conical flask typically changes as the titrant is added. The pH may increase, decrease, or remain constant depending on the nature of the reactants and products formed during the titration. The pH may reach a maximum or minimum at the equivalence point, depending on the type of titration being conducted.
