We’re asked to write the balanced ionic and net ionic equation for the acid-base reaction of HCHO2(aq) and NaOH(aq)


Before balancing the chemical reaction, let’s first write the determine the products in the reaction.

Reactants:

Formic Acid HCHO2

• Formic acid is made up of H+ ion and CHO2- ion

          • H is bonded to a non-metal so its charge is +1 → H+

          • The overall charge is of formic acid is 0 so CHO2 must have a -1 charge → CHO2-

          • The dissociation is: HCHO2(aq) → CHO2-(aq) + H+(aq)


Sodium Hydroxide NaOH

• Sodium is a metal from group 1A which forms an ionic bond as Na+

• Hydroxide is a polyatomic anion with -1 charge → OH-

• The dissociation is: NaOH → Na+ + OH-
