Question

A student adds a spoon full of of powdered sodium hydrogen carbonate to a flask containing ethanoic acid. list two main observations and note about the reaction that takes place. also write chemical equation for the reaction

Answer 1

This is a double replacement reaction and the sodium ion reacts with the acetate ion. Giving Sodium Acetate And a H+ Ion reacts with the bicarbonate ion giving carbonic acid which decomposes into water and carbon dioxide. Hence your equation will be:

Na HCO3 (aq) +CH3COOH (aq) = NaC2H302 (aq) + H20 (l) + CO2 (aq)

OBSERVATIONS;

1) a gas is liberated immediately with brisk effervescence which is CO2.

2) you can see froth on the surface of solution.
