Answer :
When creating a model of a volcanic eruption using baking soda and vinegar, the best option for personal protection is goggles.
Goggles: This choice is important because they protect your eyes from any splashes or spills during the experiment. The reaction between baking soda and vinegar produces carbon dioxide gas, which can cause the liquid to bubble and splash. Goggles ensure that your eyes are safe from any of these splashes, which is crucial for safety.
Tongs: Tongs are used for holding or picking up objects, especially hot ones, but they aren’t necessary for this particular experiment involving baking soda and vinegar.
Test Tube: A test tube is a piece of laboratory glassware, but for a model volcano, you typically use something larger to better mimic a volcanic eruption, like a bottle or a small container.
Beaker: A beaker can be used to contain liquids, but it doesn't specifically provide protection during the experiment. However, it could be useful as a container for one of the reactants.
In summary, wearing goggles is a safety measure that helps protect your eyes during the experiment. Safety is always a top priority when conducting any kind of chemical reaction, no matter how simple.
