#NaHSO_4# produces #H^+# ion in its aqueous solution, which combines with #CO_3^2-# ions (formed on ionisation of #Na_2CO_3#) to form #H_2CO_3#,an unstable weak acid.This acid readily decomposes to form #CO_2# gas.

#2NaHSO_4->2Na^+ + 2H^+ + 2SO_4^"2-"#

#Na_2CO_3->2Na^+ + CO_3^"2-"#

#CO_3^"2-" + 2H^+ -> H_2CO_3#

#H_2CO_3->H_2O + CO_2#

Equation of the net reaction

#Na_2CO_3+2NaHSO_4->2Na_2SO_4+H_2O+CO_2#
