Question

the reaction of Acetic Acid and sodium carbonate is shown below answer the following question with the help of the diagram first question which gas does come out of S and difference is the big test tube second question what is the colour change in the Lime water present in the small test tube why third question write the relative reaction

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

Answer 2

Acid is not good for skin
