Question

What happens when acetic acid is added to a tedt tube containing sadium carbonatr.Write the chemical rraction?

Answer 1

When acetic acid is added to sodium carbonate it produces brisk effervescense, water and carbon dioxide gas.

CH3COOH + Na2CO3 => CH3COONa + H2O + CO2

Gas evolved is carbon dioxide

Answer 2

When sodium carbonate is added into acetic acid or ethanoic acid it gives a sodium salt which is sodium ethanoate, brisk effervesence carbon dioxide and water

2CH3COOH + Na2CO3 ---------> 2CH3COONa + CO2 + H2O

This gas (CO2) can also be check by passing through slake limewater (Carbon Hydroxide) which turns it milky

#OBSERVATION
i. a brisk effervesence is observed
ii. an odourless and colourless carbon dioxide is released
