Procedure

➢ Using a spatula, sodium carbonate is added to ethanoic acid in a test tube

Result: Effervescence/Fizzing/Bubbles are produced that when bubbled through limewater will turn the limewater milky white

2
New cards

What gas is produced when sodium carbonate to ethanoic acid?

Carbon dioxide – only carbon dioxide turns Limewater milky

3
New cards

Write a balanced equation for the reaction of ethanoic acid and sodium carbonate

2CH2COOH + NaCO3 → 2CH3COONa + H2O + CO2

Ethanoic acid + sodium carbonate → sodium ethanoate

Acid + carbonate → salt + H2O + CO2

4
New cards

Write a balanced equation to show why carbon dioxide turns limewater milky white

CO2 + Ca(OH)2 → CaCO3 + H2O

Ca(OH)2: → limewater

CaCO3: → calcium carbonate
