1. A student mixes baking soda and vinegar in a glass. The results are a bubbly chemical reaction. Do you think any new substances are being created in this mixture? If so, how do you know?


2. Suppose this was done on top of a balance. Do you think the mass would change as the reaction proceeded?


3. What do you think would happen to the mass if the reaction took place inside a sealed plastic bag?



Answer :

(1) Because of the chemical reaction that will occur when vinegar and baking soda are combined, a new material will be produced.

(2) If the reaction is carried out in an open balance, the mass will fluctuate as the reaction continues because carbon IV gas will be emitted.

(3) The mass of the product will rise if the reaction occurs within a plastic bag because the gas produced cannot escape.

Acid and base react chemically to create a whole new compound. The end results are typically salt and water, with occasional gas emissions.

Baking soda (NaHCO3) is a basic, whereas vinegar (CH3COOH) is an acid.

CH₃COOH + NaHCO₃ → CH₃COONa + H₂O + CO

(2) If the reaction is carried out in an open balance, the mass will fluctuate as the reaction continues because carbon IV gas will be emitted.

(3) The mass of the product will rise if the reaction occurs within a plastic bag because the gas produced cannot escape.
