Why is it necessary to turn off the water pump when washing a solid in a buchner funnel?

So that all the liquid isn't immediately pulled through the filter. To wash the solid, you want the solid to interact with the liquid, to stir it, to make sure that any soluble impurities have a chance to be dissolved and removed. If you leave the aspirator on while washing, the interaction time of the solid and the washing solvent will be reduced. Add liquid, stir, and then turn the aspirator back on to remove the impurity-containing solvent.

What is the name of the solid retain of buchner funnel?
The solid can simple be called solid. The liquid collected in the buchner flask is the filtrate
What is a funnel in biology?
A funnel is used to separate an insoluble solid from a liquid.
What solid shape matches a funnel?
cone
What do you use funnel paper for?
Filtration by use of a filter funnel is a method used to filter solid particles from a liquid substance. Filter paper must be folded and fashioned into a cone shape and placed inside a funnel in order to begin the scientific process of filtration.
A substance that exists as a solid at ordinary temperature but changes to vapour on heating?
Iodine and ammonium salts sublime, their vapours then turn back into solids when cooled down. To see the sublimation, heat some iodine in a china dish and place a funnel upside down above the vapours (violet). The heated vapours become solid on contact with the funnel wall.

Why buchner filtration chosen for filtration?
To keep the solid part of a chemical mix you have made it is used for aspirin synthesis for example

cone
Why buchner funnel is faster than ordinary funnel?
A filter funnel is a funnel shaped filter that is used to separate solids from liquids. By passing the mixture of solid and liquid parts through a filter, which is either a piece of filter paper or a glass frit, the solids remain in the filter funnel and the liquid is passed into a collection flask below. A Buchner funnel is typical kind of filter funnel.See the Web Links to the left for more information about filter funnels.A funnel is a pipe with a wide, often conical mouth and a narrow stem. It is used to channel liquid or fine-grained substances into containers with a small opening. Without a funnel, much spillage would occur.
Function of the filter funnel?
The use is to separate as solid from a liquid by filtration.
Why are funnels used in experiments?
A funnel is used to separate an insoluble solid from a liquid.
What is the name of the apparatus used to put a solid into a test tube?
eat the solid first then deficate it then put it in the test tube
What does cold filtration mean?
it is where you separate a solid from a liquid using a funnel & filter paper
What is the easiest way to transfer solid from the large mouthed container to a small mouthed container?
funnel
Is washing powder a liquid?
No. As the term washing powder would suggest, it is a powder, which consists of many small solid particles.
