Question

Burette and pipette are used to measure mass.
True
False

Answer 1

Hint:Burette and pipette are lab equipment , they are used in volumetric analysis of an analyte. Burette is a glass tube having a tap at the bottom whereas pipette is also a glass tube that has a bulge at the middle .

Step by step solution :-
Burette and pipette both have gradations to measure the quantity of chemical substances in volume.

In titration pipette is very commonly used , as the titration is based on accurate measurements of volumes of chemicals , a pipette is used to accurately measure a fixed volume of liquid and is filled using a pipette filler to a line on the upper thin part of the tube.

Burette is also a laboratory apparatus used in quantitative chemical analysis to measure the volume of a liquid or a gas. Burette consists of a graduated glass tube with a stopcock ( i.e turning plug / spigot ) at one end.
Now, we conclude that both burette and pipette are used for measurement of volume.

Hence the given statement is false.

Note:- The apparatuses used for measuring mass are
-Beam balance
-Digital kitchen scale
-Weighing scale
-Hybrid spring and balance scale ( Elastic arm scale )
-Mechanical scales
-Spring scales ( Spring scale measures mass by reporting the distance that a spring deflects under a load. Spring scales measure force, which is the tension force of constraint acting on an object, opposing the local force of gravity. They are usually calibrated so that measured force translates to mass at earth’s gravity. The object to be weighed can be hung simply from the spring or set on a pivot and bearing platform.)
-Hydraulic or pneumatic scale
( they are common in high – capacity applications such as crane scales to use hydraulic force to sense mass.)
