N this experiment, you will observe the relationship between pressure and volume for gases at a constant temperature. You rememb
er that baking soda and vinegar react to form a gas. We will use this reaction in this experiment. Start by adding approximately twenty milliliters of vinegar to a bottle. Now you pour about half a teaspoon of baking soda into the balloon, using a funnel. Attach the end of the balloon to the top of the bottle. Carefully lift up the balloon up to let the baking soda fall into the vinegar in the bottle. Observe what happens.
