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.
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!
Why must have gross reading in titration process?
to get rough volume....
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.

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 titration in chemistry?
Completely titrated means it reached the stoichiometric point (usually pH=7). Simply means neutralized.
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 is the precaution step of acid base titration?
1.The beaker,pipette and the flask should be washed properly with distilled water. 2.Pipetting has to be accurate in order to avoid excess addition of the titrating agent. 3.The flask containing the indicator (phenolphthalein or methyl orange) must be shaken well while acid is added to it. 4.The acid should be added dropwise. 5.Contamination should be avoided. 6.Excess of indicator should not be used. 7.The flask into which acid is added dropwise should be removed as soon as the indicator changes color. 8.Readings should be taken avoiding the parallox error.
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 does concentration affect a titration?
It is easier to answer this by using examples. Let us suppose we have 4g of NaOH in 100 mls of waste water (4%). Titrating with 1M HCl would require 100ml of titrant. That would thus mean we would need 1000ml of 0.1M HCl titrant run from a buret which is extremely impractical. The concentrations thus affect volumes and thus titration flask sizes etc. It also would affect the time taken and the practicality.
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.
