NaOH + NaHCO3 -> Na2CO3 + H2O, with sodium carbonate being still caustic, even if less than NaOH. As the current accepted answer correctly pointed out, the bicarbonate ion dissociates into a proton and a carbonate ion, and that an equilibrium between the bicarbonate ion and the carbonate and hydrogen ion is established. The more toxic, corrosive, or flammable a material is, the less likely that the spill can be defined as "simple". What ratio of bicarb to vinegar do I need in order for the result to be pH neutral?
