Question

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?

Answer 1

Heather has to do a titration with the acid-base reaction. She would need a complete buret assembly that contains, a buret, a buret clamp and a ringstand. She would also need an erlenmeyer flask and of course, a volumetric pipet with its pipet bulb.

Step-by-step explanation:

Answer 2

Burette.

Step-by-step explanation:

The addition of base to an acid is generally done during titration.

To add base into acid precisely, we need burette clamped into burette stand.

The general capacity of burette is 50mL, and the least count is 0.1 mL.

The acid should be taken in conical flask.

The acid can be poured into the flask with the help of pipette fitted with a pump.
