Stoichiometry - A Balancing Act Objective: To determine certain ratios between solution A and solution B and the amount of precipitate created by each reaction according to its ratio. Hypothesis: The change in ratios of solution A and solution B will affect the amount of precipitate. Procedure: 1. Measure the height of one of the wells with a ruler. (OK- its exactly 10 mm) 2. Measure 9 mm of solution by mixing equal amounts of solution A with solution B, using the pipette provided, into the well. This will be the control variable. 3. Repeat several times, using differing ratios of each solution. 4. Wait several (5-10) minutes, then measure the height of each precipitate with the ruler (to the best of your ability). 5. Record all observations. Data and Observations: Table A Other observations: When mixed (no matter the ratio), the solution yielded a yellow color, with a yellow precipitate. The brilliance...
