Answer 2

Answer:

• The instrument is used to transfer a small fixed volume of liquid is known as Burette.

Explanation:

• Burette or buret is the instrument used for transferring a small fixed volume of liquid.

• This instrument also help in measuring the volumes of the liquid.

• This instrument is made up of glass tube, and also stopcock valve helps control the flow of liquid.

There are two types of instruments in burette:

1) Volumetric burette.

2) Piston burette (Digital burette) .

Parts of a normal burette:

1) Volume markings.

2) Stopcock.

3) It has a long tip.

Volume markings:

• This looks like a scale, this helps the burette to measure and mark the volume of the liquid.

Stopcock:

• This looks like a strip and also helps in handling and controlling the flow of liquid.

Tip:

• It's tip at the bottom it's quite shape and it's attact into the stopcock valve.

Note:

• Both the types of burette instrument are used for different purposes.
