Crystal Violet Lab
The purpose of the lab is to determine the rate law for the reaction of crystal violet (CV)
and sodium hydroxide (NaOH).
Students should propose the best solvent for separation of the mixture
Rf = Distance by dye / Distance by solvent
Qualitative Analysis Lab
To identify the positive ions in two unknown solutions.
Data & Analysis:
Analysis of Group 1 Ions
Confirmation of Lead
No lead present (no yellow precipitate
Medicine Half Life Lab
To find the half life and dosage of the following medications to better understand how
they work in ones bodies.
Half-life and Dosage
HL=2 to 3 hours, Dosage=650 mg every 4 hours
Prepare an aqueous solution of sodium hydroxide to target a molar concentration.
Determine the exact concentration of the NaOH solution by titrating it with a solution of
Freezing Point Lab
Find the freezing point of the pure solvent.
Determine the lowering of the freezing point when a solute is added.
Mass of Lauric Acid
Mass of Benzoic Acid
