Question

A student uses the apparatus to determine the concentration of a solution of hydrofluoric acid. Which component will

Answer 1

Answer:

1. water and a salt

2. Magnesium hydroxide reacts with HCl to produce a solution that is neutral.

3. titrant

4. 0.08 M

5. indicator

Explanation: I did it

Answer 2

When determining the concentration of an acid solution, the titrant would usually be put in the burette while the analyte would be in the conical flask.

The titrant is usually a known solution while the analyte would be the unknown solution.

In order to determine the concentration of a solution of hydrofluoric acid, the acid would need to be titrated against a suitable base of known concentration using a suitable indicator to indicate the endpoint of the neutralization reaction.

Thereafter, the volume of the titrant used would be recorded and used to find the concentration of the acid (the analyte).

Thus, since the base would be known, it would be the one in the burette while the hydrofluoric acid would be the one in the conical flask.
