Question

the passage below describes an experiment. when baking soda and vinegar are combined, they create bubbles of carbon dioxide gas. kevin combined baking soda and vinegar in 12 different beakers. in each beaker, he placed two tablespoons of baking soda and one tablespoon of vinegar. he used rice vinegar in four of the beakers, white vinegar in four, and apple cider vinegar in four. kevin watched the beakers and recorded how long each mixture bubbled. identify the question that the experiment can best answer. does the amount of vinegar added to baking soda affect how long the mixture bubbles? does the type of vinegar added to baking soda affect how long the mixture bubbles?

Explanation:

Kevin used the same amount of baking - soda and vinegar in each beaker but different types of vinegar (rice, white, apple cider). He recorded how long each mixture bubbled. So the experiment is focused on the type of vinegar, not the amount.

Answer:

Does the type of vinegar added to baking soda affect how long the mixture bubbles?
