Expert Solution
Step 1

The required reaction is :

CH3COOH + NaHCO3 = CH3COONa + H2O + CO2

equal moles of sodium bicarbonate reacts with acetic acid.

                  CH3COOH + NaHCO3 = CH3COONa + H2O + CO2Initial          5% v/v             0.626Change           -x               -x               +x                             +xEquilibrium  5%-x            0.626-x         x                                   xtherefore equilibrium concentration of bicarbonate =0.626-[CO2]     or, bicarbonate reacted =[CO2]
