Question

why trimethylacetic acid dose not evolve carbondioxide gass with the treatment na2co3solution?

Answer 1

Hey mate here is your answer ..

This is because for carbon dioxide gas to be evolved from sodium bicarbonate, the acid must be stronger than the bicarbonate ion, HCO3-, in order to protonate it, and form carbonic acid, which rapidly dehydrates to evolve carbon dioxide gas. Hence the equation (should the acid be stronger than HCO3-) would be:

HCO3- + H+ => H2CO3 <=> CO2 + H2O
