CH32 – Virtual Chemistry

Date

• Friday, March 30th

Quick Idea – Standardization

• know approximate molarity
• titration is performing to determine concentration
• focus: reducing uncertainty and adding sig figs
• NOTE: “0.1 M” indicates a number known to +- 50%

Virtual Lab Coaching

• walk-through
• replicating “real lab”
• recording information shoudl be “lab like”

Class Time

• working on in-class titrations
• Load the “ACid Base Prelab” homework
• practice on “Problem 1”
• this is not something to be collected

Homework

• Complete Problem 3 (Prelab Exercises)
• record information as if you can turn in
• pay attention to digits and SF
• what is your answer?
• two titrations?
