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...

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 ...

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 4: Molarity of Vitamin C - Portage Learning Purpose: The purpose of this lab is to determine a better understand of solutions and concentrations relating to vitamins, specifically vitamin C or ascorbic acid. In order to do so, we measured the vitamin C in a few different fruits to determine the concertation of vitamin c in each. Procedure: Part 1: Determining the vitamin c concentration of iodine 1. Iodine was placed in a buret. 2. A solution was made from the commercial vit...
