A student carried out two titrations using an NaOH solution of unknown concentration in the burette. In one titration, she weighed out 0.2458 g of KHP (see page 166 .) and transferred it to an Erlenmeyer flask. She then added 20.00 mL of distilled water to dissolve the acid. In the other titration, she weighed out 0.2507 g of KHP but added 40.00 mL of distilled water to dissolve the acid. Assuming no experimental error, would she obtain the same result for the concentration of the NaOH solution?

Solution Summary: The author explains that acid–base titrations are useful in determining the concentration of an unknown acid or a base.
A student carried out two titrations using an

solution of unknown concentration in the burette. In one titration, she weighed out 0.2458 g of KHP (see page 166.) and transferred it to an Erlenmeyer flask.
