Question

what happens when dilute hydrogen acid is added to sodium carbonate write a balanced chemical equation of the reaction involved

Answer 1

hey..

Na2CO3 + HCl ----> NaHCO3 +NaCl

As more HCl is added the sodium bicarbonate reacts with it to produce CO2, NaCl and H2O;-

NaHCO3 + HCl ----> NaCl + CO2 + H2O

:)

Answer 2

An aqueous solution of sodium sulphate (sodium carbonate is a base whilst dilute H2SO4 is an acid), plus CO2 gas effervescing out of solution

so H2SO4(dil.)+Na2CO3---->Na2SO4+H20+CO2
