Which piece of glassware should never be used for measuring the volume of a liquid but can be used for heating and making solutions?

The most commonly used glasswares in laboratories are beakers, measuring cylinders, volumetric flasks, pipets and buretes.

Among them, the main purpose of using measuring cylinders, volumetric flasks, pipets and buretes is to measure a definite volume of the liquid. Also they are not appropraite for the heating purpose.

On the other hand, beakers are roughly graduated , so can't measure volume accurately. And they are made up of pyrex and thus can be heated.

Therefore, the piece of glassware  that should never be used for measuring the volume of a liquid but can be used for heating and making solutions is  a BEAKER.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
