Question

Perform and describe an activity in your Activity-Folder to show the

evolution of gas during the reaction between baking soda and vinegar and

identify the evolved gas..
​

Answer 1

Answer:

NaHCO3(s) + CH3COOH(l) → CO2(g) + H2O(l) + Na+(aq) + CH3COO-(aq)

Explanation:

Using the funnel, add the baking soda to each balloon (two people may be needed for this; one person to hold the balloon open and the other person to put the baking soda inside of the balloon).

Pour the vinegar into the bottle.

Carefully fit the balloon over the bottle opening (be careful not to drop the baking soda into the vinegar yet).

Once the balloon is fitted snugly on the nozzle, hold up the balloon and allow the baking soda to fall into the vinegar.

Observe the chemical reaction and effect on the balloon.

Record observations.

Answer 2

Answer:

When baking soda is mixed with vinegar, something new is formed. ... The solid baking soda was placed in liquid vinegar producing carbon dioxide gas, which is evident because of the formation of bubbles in the foaming mixture. Eventually all of the solid dissolved and reacted producing a new liquid solution.
