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
To determine the concentration of potassium hydroxide in the reaction, the student can perform a titration. Firstly, the student needs to fill the burette with the 0.1 M solution of hydrobromic acid. Then, the student slowly adds the hydrobromic acid into the flask containing the 25 mL of potassium hydroxide until a color change or an indicator shows that the reaction is complete. The volume of hydrobromic acid used in the titration can be used to calculate the concentration of potassium hydroxide using the balanced chemical equation and stoichiometry.
