Question

in an experiment to study the properties of Acetic Acid answer the following question name the substance which on addition to acetic acid produce carbon dioxide and how carbon dioxide as it is tested in laboratory

Answer 1

Sodium hydrogencarbonate on reaction with acetic acid releases carbon dioxide gas. NaHCO3 + CH3COOH → CH3COONa + H2O + CO2 Test for carbon dioxide: The presence of carbon dioxide can be tested by bringing a burning splinter near the mouth of the cylinder containing carbon dioxide – it gets extinguished. If carbon dioxide is passed through limewater, it turns milky white. Ca(OH)2 + CO2 → CaCO3 + H2O



I think that this will help you

Answer 2

Answer:

a) NaHCO₃

Chemical reaction as :

CH₃COOH + NaHCO₃ ⇒  CH3COONa + H₂O + CO₂

b) CO₂ on passing through lime water turns milky.
