Agenda

  1. Investigation: Titrating an Acid — three trials that agree, then average
  2. Compare the room’s concentrations — that spread is your uncertainty
  3. Task launch: The Water Report — read the criteria before planning
  4. Decide which measurements your report genuinely needs
  5. Bench time: begin sampling and your first trials

Things to do before our next class

  • Finish three titration trials that agree to within 0.2 mL.
  • Journal: the step in the titration you least trust, and one change that would tighten it.
