Use the reaction to complete the activity.

KOH + HBr → KBr + H2O

A student sets up a titration apparatus with 25 mL of potassium hydroxide in the flask. In three to five sentences, explain how the student can use a 0.1 M solution of hydrobromic acid to determine the concentration of potassium hydroxide in the reaction.

In order to determine the concentration of the hydrobromic acid, the student would need to put some amount of the acid into the burette, note the initial burette reading, and then titrate it against the potassium hydroxide in the flask using a suitable indicator to indicate the endpoint of the reaction.

Thereafter, the volume of hydrobromic acid required to neutralize 25 mL of the potassium hydroxide would be obtained. The following equation can then be used to obtain the concentration of the hydrobromic acid:

Ca = [tex]\frac{Cb.Vb.Na}{Va.Nb}[/tex]

Where Ca - concentration of hydrobromic acid, Va - volume of hydrobromic acid used in titration, Cb - concentration of potassium hydroxide, Vb - volume of potassium hydroxide, Na - stoichiometric number of moles of hydrobromic acid, and Nb - stoichiometry number of moles of potassium bromide.
