How to clean a burette before fill it with hydrochloric acid?
Rinse with distilled water and blow dry with compressed air.
Is a burette the best tool to measure acid?
Yes, a burette is the best tool for measuring acidYes, a burette is the best tool for measuring acid
Why rinse the burette with distilled water?
To remove any trace of other chemicals that may still be in the burette.
What is an acid burette?
If you have an acid in your conical flask then the base will go into the burette. The burette is used to measure the amounts of base you are adding and therefore you will be able to determine the end point which is normally determined by a colour change.
Why it is preferred to take acid in burette during acid base titration?
The burette can be filled with either acid or base. The acid will go into the burette only if you want to titrate a base , i.e. you don't know the concentration of the base and want to find out. The solution of known concentration goes always into the burette (in order to be able to measure the volume taken to complete the reaction) and so if you wanted to find out the concentration of an acid you would put the base into the burette.
Why ist necessary to rinse the clean burette before filling it with the unstandardised sodium hydroxide solution?
It is a rule of safety in chemistry: to remove any micro-drops of water from the pipette.
What is acid buret?
An acid burette is an acid which has more than one compound.
How do you clean a burette with stopcock stuck in it?
Rinse with hot water outside try to rinse only outside, stop cork will be loosed and pulled out easily.
What indicators can be used in titration?
Acid Alkali Indicator Details Strong Strong Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised) Weak Strong Phenolphthalien pipette acid, and burette alkali (change from colouless to salmon pink when neutralised) Strong Weak Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised) Acid Alkali Indicator Details Strong Strong Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised) Weak Strong Phenolphthalien pipette acid, and burette alkali (change from colouless to salmon pink when neutralised) Strong Weak Methyl Orange pipette alkali, and burette acid (change from yellow to light pink when neutralised)
Is it necessary to rinse the conical flask with some standard solution of oxalic acid before use?
I believe it is necessary to rinse the conical flask with oxalic acid before use, unless you are sure that the conical flask is really clean and dry before use. However to prevent having any types of unwanted chemical reaction when you pour the oxalic acid in the flask, it is best to rinse it with oxalic acid before use, so that there will not be errors like e.g. there is no pinkish color formed in the solution when you add the color indicator in the oxalic acid when doing titration.
What is the use of acid and base burette?
The general use of acid/base burettes I am familiar with is to determine the concentration of either the acid or base from the known concentration of the other solution. The two burettes are set side by side, and a quantity of acid is placed into a Erlenmyer flask from the acid filled burette and then the solution from the base filled burette is run into the flask along with indicator to the point of color change. By the amount titrated one can use a simple equality to find the concentration of the unknown solution.
What are the precaution steps in during titration?
You should only remember to rinse the equipment with the suitable liquid. Like burette with HCL.
