Questions
1) Titrations are often done with an Erlenmeyer flask without a stir bar (hand swirled instead). Why is a

A2) What if tap water is used to dissolve the KHP, is this a concern? What are possible problems with this
choice of solvent? Explain.

gentle heating before use). If it did absorb water what would be the outcome for the molarity of the base
relative to what you found? Explain.
