- Ch 2 Podcast 2 (Naming) with Naming ppt, Mini quiz on Naming tomorrow
- Do the prelab on Quick Ache Relief lab, due tomorrow
Guidelines for completing the prelab:
Step 1: Compare and record the solubilities of starch, acetaminophen and acetylsalicylic acid (aspirin) by checking the MSDS for each.
Step 2: Go over liquid-liquid extraction animation1 and 2
Step 3: Read about drying an organic solvent.
Step 4: Do the calculations.

Sucrose is insoluble in organic solvents such as ethyl acetate
Acetaminophen and aspirin (acetyl salicylic acid) are soluble in ethyl acetate and are relatively insoluble in water.
Aspirin will react with sodium hydrogen carbonate (NaHCO3) to form sodium acetyl salicylate, which is soluble in water.
Acetaminophen does not react with aqueous NaHCO3
Sodium acetyl salicylate can react with 6M HCL to form water and insoluble apirin.
