Agenda
- Investigation: Titrating an Acid — three trials that agree, then average
- Compare the room’s concentrations — that spread is your uncertainty
- Task launch: The Water Report — read the criteria before planning
- Decide which measurements your report genuinely needs
- 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.
