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.

How to prepare a standard solution of potassium iodate?
it is primary standard........ but before making solution dry it at 120. C
Why is it necessary to standardize the NaOH solution before titration?
It allows the concentration of the NaOH to be known.
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 the pH of the solution before the titration?
This depends on what kind of solution you are about to titrate.
Why is the vinegar diluted before titration?
1. The advantage in diluting the solution before titration is that it allows for greater accuracy in the titration; this is because the color change in the solution is easier to observe if it is a dilute solution.

Why is it necessary to dry residual water with calcium chloride before distillation of tert-butyl chloride?
Tert-butyl chloride is not soluble in water. A solution is necessary to perform a distillation.
Is olive oil homogeneous or heteorgenous?
Cooking oil is an example of a homogeneous mixture, because it has the same consistancy throughout. There is no need to shake it up before using. Shaking is necessary when the contents of a solution settle at the bottom of a solution, such as in Italian salad dressing.
Is it necessary to use an enema before a sphincterotomy Won't the miralax cleanse the day before do the same thing?
An enema is still the preoperative standard. A Miralax cleanse is not sufficient in the vast majority of cases.
Why is it necessary to study order of operations and laws of operations before you solve equations?
Because if you did operations in an impermissible order, or violated laws of operations, then your solution to the equation is wrong.
