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? a graduated cylinder an eye dropper a beaker a buret

Explanation:

A buret is a laboratory tool used for precise dispensing of liquid volumes. It allows for drop - by - drop addition of a solution (in this case, the basic solution) and can measure the volume added with high precision (usually to the nearest 0.01 mL). A graduated cylinder is used for measuring larger volumes of liquid but is not as precise as a buret for drop - by - drop addition. An eye dropper can add liquid drop - by - drop but is not used for precise volume measurement. A beaker is mainly used for holding and mixing liquids, not for precise volume measurement or drop - by - drop addition.

Answer:

a buret
