Question

11. When baking soda is mixed with vinegar, bubbles are formed with evolution of a gas.
a. Name the gas and how will you test for it?
b. What type of change is it and define the change?
c. Write a word equation for the above mention reaction?

please tell the answer quickly I will mark you as BRAINLIST ​

Answer 1

Answer:

co2gas

by passing through the lime water

if it change into milky white

then it confirms that it is co2gas

Answer 2

Answer:

PLEASE MARK AS BRAINLIEST.

1. The reaction between baking soda (sodium bicarbonate) and vinegar (dilute acetic acid) generates carbon dioxide gas, which is used in chemical volcanoes and other projects. The most effective way to test for CO2 is to bubble the gas through "limewater", a diluted solution of calcium hydroxide (slaked lime). When you bubble carbon dioxide through the solution, it forms a solid precipitate of calcium carbonate – chalk or limestone.
2. Adding vinegar to baking soda is a classic example of a chemical change where sodium bicarbonate (baking soda) is reacted with acetic acid and water (vinegar) releasing carbon dioxide and making sodium acetate.
3. Acetic acid present in vinegar will readily react with baking soda (sodium bicarbonate) to form sodium acetate with the effervescence of carbon dioxide. The equation for the reaction is: CH3COOH + NaHCO3 = CH3COONa + CO2 + H2O.
