Heather is doing an acid-base reaction. She has 25.00 mL of hydrochloric acid of unknown concentration in a flask. She wants to add a basic solution to the acid drop by drop, until all the acid has reacted.

Which tool would be best for adding the basic solution dropwise and for most precisely measuring the volume of solution added?

a graduated cylinder
an eye dropper
a beaker
a buret

Respuesta :

A burette would be the best tool for the required use.
The process described is called a 'titration'

Answer: a buret

A graduated cylinder and a beaker cannot be used. This is because the basic solution needs to be added drop by drop. This is not possible using a graduated cylinder or a beaker because it is difficult to pour drop by drop from these. An eye dropper cannot be used because it does not measure the volume being added.

A buret would be the best choice because it precisely measures the amount being added and we can add the basic solution to the acid drop by drop.
