Part B
Next, you'll test your hypothesis by examining the reaction times of vinegar and baking s
water using four different concentrations of the reactants. You'll vary the concentrations
tablespoon (7.5 milliliters), 1 tablespoon (15 milliliters), 1 tablespoons (22.5 milliliters), a
tablespoons (30 milliliters) of water. Note that you will use the same amounts of vinegar
soda for each trial.
Gather all the materials, and proceed with these steps:
1. Boil at least 1 cup (240 milliliters) of water on a stove, on a hot plate, or in a microw.
2. Measure and record the actual temperature of the water.
3. Measure the required amount of boiling water into the cup.
4. Add teaspoon (1.5 grams) baking soda to the water, and stir until it is dissolved. T
solution will be clear.
5. Measure out 1 tablespoon (15 milliliters) of vinegar, but do not pour it into the cup
6. Very quickly, do all of the following:
a. Pour the measured vinegar into the cup.
b. Start the stopwatch.
