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.
What is titrate?
Titrate is a process used in chemistry to determine the concentration of a substance in a solution. It involves slowly adding a solution of known concentration (titrant) to another solution until a reaction is complete, allowing the concentration of the unknown substance to be calculated.
Why it is preferred to take acid in burette during acid base titration?
Well, isn't that just a happy little question! Using the acid in the burette during an acid-base titration allows for better control of the amount of acid being added to the base solution. This helps us achieve more accurate and precise results, ensuring our titration is successful and our painting... I mean experiment, turns out just right. Just remember, there are no mistakes in science, only happy accidents!
What is blank reading for titration of iodine value?
Blank reading is the initial reading taken before adding the sample in the titration of iodine value. It represents the baseline value of the titrant solution without the presence of the sample. This reading is used to ensure accuracy in calculating the iodine value of the sample by subtracting it from the final reading after titration.
What is a titration?
A titration is the use of carefully measured amounts of a known solution to determine the concentration of another. They often involve acid-base neutralisation or oxidation-reduction reactions (examples would be sodium hydroxide with hydrochloric acid, or permanganate with an iron solution). The main part of the system is the burette, a large graded tube with a controllable variable nozzle at its end. This nozzle is used to add different amounts with great precision to the solution being tested, so that an exact reading can be made - if done correctly, the titration's accuracy is limited only by the scale on the burette. A sample of the test solution (collected using a pipette with a known volume and high degree of accuracy; the sample is called an aliquot) is placed in a container, usually a conical flask, under the burette. The burette is filled with known solution, i.e. one where the concentration is know to another high degree of accuracy. The two are mixed slowly and allowed to react - for acid-base titrations an indicator will be added to the flask, for redox the solution which will change colour is put in the burette. This is continued slowly until the solution will barely react with that from the burette. At this point the amount of solution taken from the burette is recorded. Ideally, the next slightest drop of burette solution will cause a change in colour of the solution that does not change at all. If not, the new recording is made and the last step repeated. This amount is a titre. The whole experiment is repeated several times. The data is collected and averaged out. From this, an amount of known solution used, an amount of tested solutio used and eventually a concentration can be found.

What precautions should be taken when using 6.0m HCl?
1.) Safety glasses to shield your eyes from any contact with acid 2.) Pouring the solution ( into maybe a conical flask, beaker etc.) at eye level to avoid spillage.

How can the effect of changing the mass of a catalyst on the rate of a reaction be investigated?
You can investigate what happens if you use more catalyst for the decomposition of hydrogen peroxide solution reaction. You will set the experiment up by connecting a gas syringe to a conical flask and adding the required substances into the flask. You will then record the time taken to produce a certain amount of gas in the syringe.Safety!Make sure you wear eye protection at all times.You will need:100 cm3 conical flask attached to a 100 cm3 gas syringebungstop clockhydrogen peroxide solutionmeasuring cylinderpowdered manganese dioxide (harmful)top pan balanceeye protectionMethodWeigh out 0.5 g of manganese dioxide powder into the conical flask.Add 50 cm3 of hydrogen peroxide solution and insert the bung. Start the clock straight away and swirl the flask once to mix the powder and the liquid.Twist the plunger of the gas syringe gently to stop it sticking.Measure the time taken for 50 cm3 of gas to be produced.Look carefully at the liquid left in the flask.

What is titration in chemistry?
Completely titrated means it reached the stoichiometric point (usually pH=7). Simply means neutralized.
How do you prepare phenolphthalein indicator for titration?
Upon swallowing such a solution, you would collapse almost immediately and lose consciousness within 10-20 seconds. Death would follow in a matter of minutes. With such a massive dose taken, any medical assistance, no matter how aggressive, would prove futile. A gram mixed in with about 4 to 8 oz water would render you unconscious within 15-45 sec (depending on your body) and without medical attention you would be dead within 30-45 min.
What is the Procedures for testing Active clay in Green Sand?
yeah,sure.its so simple to find out the active clay in green sand.Active clay means ,the total active amount of clay(bentonite) present in a sample of green sand.Test Procedure:-Take some sample of green sand and keep it in a oven for 1hr at a temp of 100 deg celsious.This procedure is to make the sand free from moisture.Measure 5gms of this sand after taken from oven and put it in a conical flask with a 50ml of distilled water.Then again keep this in the oven for 10-15 min to boil the solution.Take this from the oven and keep it for a few mins to get cool.Then pour 2ml of diluted h2so4(sulphuric acid) in to the same mixture and place the flask under a burette filled with methylene blue.Then start the titration by leaving methylene blue to the flask containing the above said solution of sand.Shake the flask continously to allow the methylene blue to equally mix with the sand.Stop the titration alternately and place a single drop of solution from the flask in to a filter paper.If you find a light blue ring colour around the dark blue colour(colour of methylene blue) , its the end of itration and read the burette reading.Other wise you can continue titration until you get as above said.calculation:-for example , suppose burette reading is 74there fore active clay = 74/5 =14.8% (for 5gm sample of sand)Hope you understood the procedureThank you.
