2 if the base buret were not rinsed with naoh prior

This preview shows page 4 out of 4 pages.

2. If the base buret were not rinsed with NaOH prior to filling (after DI water rinse), would the calculated molarity of the base be too high, too low or unaffected? Explain.
3. If the liquid splashed out of the Erlenmeyer flask during the titration before the endpoint was reached, would the calculated molarity of the base be too high, too low or unaffected? Explain.
4. If the air bubbles were not expelled from the base buret tip and remained in the buret prior to titration, would the calculated molarity of acetic acid be too high, too low or unaffected. Explain.
