Experiment #: 6 
Title: Electrochemistry 
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 light) 
c...

CHEM 104 Experiment 5: Buffers - Portage Learning Purpose: The purpose of this lab is to determine how buffers affect the pH of a solution in order to observe how a buffer is resistant to pH changes. Additionally, we determined how enzymes activity is affected by pH. Procedure: Part 1: Determine pH of sodium acetate in water & buffer 1. 2 pH electrodes are place in 2 separate beakers, one filled with tap water & one is filled with a pH 7 buffer (both have an approximate pH of 7) 2. A scoop of s...

Title: Urinalysis 
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 
2. Add ...
