How do you prepare 0.1N Na2S2O3 solution?
To prepare a 0.1N Na2S2O3 solution, dissolve 24.98 grams of Na2S2O3·5H2O (sodium thiosulfate pentahydrate) in distilled water and dilute to 1 liter in a volumetric flask. This will give you a 0.1N (normal) solution of Na2S2O3.
How do you 0.02 sodium thiosulfate prepared?
To prepare 0.02M sodium thiosulfate solution, weigh out the required amount of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) or anhydrous sodium thiosulfate (Na2S2O3). Dissolve this in distilled water and make up the volume to the desired concentration. Make sure to use a volumetric flask for accuracy and precision in preparing the solution.
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 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.
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 should the flask be covered not stoppered?
Covering the flask instead of stoppering it allows for any gas produced during the reaction to escape, preventing pressure build-up that could lead to the flask exploding. Stoppering the flask could trap the gas and result in a dangerous situation.
What does sandy drink from her flask?
It is not explicitly stated what Sandy drinks from her flask in the movie. It is implied that she carries alcohol in it, as she is shown drinking from it frequently during the film.
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.
Which flask is used or heating solutions?
A heat-resistant flask, such as a borosilicate glass flask or a round-bottom flask made of heavy-duty glass, is commonly used for heating solutions in a laboratory setting. These flasks can withstand high temperatures and are designed to minimize risk of breakage during heating.
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.
What is the use of iodine flask?
An Iodine Flask is essential an Erlenmeyer Flask with a stopper used for the wet chemical analysis "Iodine Determination" . This analysis is typically performed on fatty acids, oils and shellac varnishes.
What is another word for triangular flask?
Another word for a triangular flask is a conical flask.
