Question

Mention two visible changes that occur when vinegar and baking soda is mixed in the first test tube and A is passed through B in the second test tube.​

Answer 1

Answer:

It creates a fissing sound

Answer 2

Two visible changes occur when vinegar and baking soda is mixed in the first test tube and A is passed through B in the second test tube are the formation of bubbles and foam and an impressive eruption.

• Vinegar and Baking soda chemically react as out of the two one is acid and the other is base. Sodium bicarbonate is the other name of this basic compound known as baking soda.
• A diluted solution is vinegar that comprises acetic acid. There are two separate reactions of the reaction between vinegar and baking soda.
• Out of which the acid-base reaction is the first reaction. Hydrogen ions present in the vinegar reacts with the ions of sodium bicarbonate present in the baking soda when both baking soda and vinegar are mixed.
• As an outcome of this first reaction is the formation of two new chemicals are sodium acetate and carbonic acid.
• A decomposition reaction is the second reaction of this chemical reaction in which the result of the initial reaction i.e the formation of carbonic acid immediately starts to decompose into carbon dioxide gas and water.
• This gas rises above the mixture on the surface of it and forms bubbles as well as foam which is the first visible change that a person can see on mixing vinegar and baking soda.
• Another visible change is a huge eruption that occurs on mixing a large quantity of vinegar and baking soda that also in a small container.

Hence, the formation of foam and bubbles as well as eruption are the two visible changes of the mixture of baking soda and vinegar.
