CHEM 104 Experiment 8: Urinalysis - Portage Learning Purpose: The purpose of this lab is to carry out several experiments to evaluate the chemical makeup of a simulated urine sample. Procedure: Part 1: Chloride (Cl- ) 1. Prepare a mixture of AgNO3(silver nitrate) & Cl- solutions 2. These are both colorless solutions 3. Combine the solutions & note how they turn cloudy & form a white precipitate Part 2: Phosphate (PO3 -3) 1. Prepare a mixture of PO4 & (NH4)2MoO3 (Ammonium dimolybdate) solutions ...

CHEM 104 Experiment 7 Organic Synthesis - Portage Learning Purpose: The purpose of this lab was to determine the process of synthesizing various carboncontaining organic products including aspirin, urea, & salicylic acid. In doing so, we were also able to calculate the percent yield in each of these experiments. Procedure: Part 1: Synthesis of aspirin 1. Placed 2.0 g of salicylic acid & placed it in a flask 2. 5.0 mL of acetic anhydride was then added to the flask & mixed 3. 5 drops of sulfuric...

CHEM 104 Experiment 6: Electrochemistry - Portage Learning Purpose: The purpose of this lab was to study how redox reactions occur & to determine how conductivity can occur between metals & how we can predict if it will react or not. Procedure: Consider: Cu2+ + 2e- -> Cu(s) = reduction Fe(s) -> Fe2+ + 2e- = oxidation Part 1: 1. Utilizing a lightbulb device, we tested the conductive of the following items: a. Metal cylinder  good conductor (bright light) b. Water  poor conductor (no ...
