Odgovor:

# "CH" _3 "COOH" _text (aq) + "NaHCO" _3 "" _ text (s) -> "CH" _3 "COONa" _text (s) + "H" _2 "O" _text (l) + "CO" _2 "" _ text (g) #

Pojasnilo:

# "Acid" + "Vodikov karbonat" -> "Salt" + "CO" _2 + "H" _2 "O" #

V tem primeru imamo # "CH" _3 "COOH" # in # "NaHCO" _3 #

Nastala sol je # "CH" _3 "COONa" # ker kislina daje proton. To nas pusti # "H" ^ + # in # "HCO" _3 "" ^ - #namesto oblikovanja # "H" _2 "CO" _3 #, tvorijo # "H" _2 "O" # in # "CO" _2 #, ki daje odziv na:

# "CH" _3 "COOH" _text (aq) + "NaHCO" _3 "" _ text (s) -> "CH" _3 "COONa" _text (s) + "H" _2 "O" _text (l) + "CO" _2 "" _ text (g) #
