Feedback

• what worked?
• what did not work?
• what did you learn?

Collecting LNB

• will grade as 4 lab reports (as discussed before)
• hopefully you see the “pattern” I am coaching RE: lab reporting
• will use this moving ahead

New Idea: Gravimetric Analysis

• use mass of precipitate to determine something about reactant
• EX1: p. 183 (63) – molar mass
• EX2: p. 183 (64) – percent of sample

Homework

• No Homework
