Final answer:
The prediction about the reaction of baking soda and vinegar is an example of a hypothesis. It suggests a chemical reaction that produces carbon dioxide gas and results in the pH of the mixture becoming more neutral.
Step-by-step explanation:
The statement "If I mix baking soda with vinegar, then it will result in bubbles" is an example of a hypothesis. A hypothesis is a proposed explanation based on limited evidence as a starting point for further investigation. It is often formed as an if/then statement to predict what may happen in a given condition. For instance, if the hypothesis about the reaction between baking soda and vinegar is correct, and they are mixed, then the mixture will bubble due to the production of carbon dioxide gas during the chemical reaction.
When baking soda (sodium bicarbonate) and vinegar (acetic acid) are mixed, the chemical reaction between these substances produces carbon dioxide gas, water, and dissolved substances. This reaction is characterized by the production of gas bubbles and is a visual cue that a chemical reaction has occurred. Additionally, pH of the resulting solution will typically become more neutral compared to the initial acidic pH of vinegar because the basicity of the baking soda will partially neutralize the acidity of the vinegar.
