Question

A student added small amount of ethanoic acid to sodium bicarbonate

Answer 1

Ch3cooh +NaHco3 —> Ch3cooNa + H2o + co2 ( with brisk effervescence)

Answer 2

ethanoic acid= CH3COOH

sodium bicarbonate= NaHCO3

When ethanoic acid is added to sodium bicarbonate salt, sodium acetate is formed and CO2 is released with brisk effervescence (brisk bubble formation).

Here is the equation :

CH3COOH + NaHCO3 → CH3COONa + CO2 ↑ + H2O

(acetic acid)  (sodium       (sodium acetate)

                    bicarbonate)
