X = CH3COONa
The gas evolved = CO2
When ethanoic acid reacts with sodium hydrogen carbonate with the production of sodium ethanoate and producing carbon-di-oxide gas.
CH3COOH + NaHCO3 → CH3COONa + H2O + CO2
Set up the experiment as shown in the figure.
- Take a spoon full of Sodium Hydrogen Carbonate in a test tube and add 2ml of dilute ethanoic acid.
- Brisk effervescence occur in testtube.
- Pass the produced gas into lime water
- Lime water turns milky confirming the evolution of CO2
