<unk>  is an amphoteric compound. Aqueous solutions are mildly alkaline due to the formation of carbonic acid and hydroxide ion: :HCO + H2O → + OH−<unk>  can often be used as a safer alternative to<unk>  hydroxide, and as such can be used as a wash to remove any acidic impurities from a "crude" liquid, producing a purer sample. Reaction of<unk>  and an acid produces a salt and carbonic acid, which readily decomposes to carbon dioxide and water:<unk>  + HCl → NaCl + H2CO3 :H2CO3 → H2O + CO2(g)<unk>  reacts with acetic acid (found in vinegar), producing<unk>  acetate, water, and carbon dioxide:<unk>  + CH3COOH → CH3COONa + H2O + CO2(g)<unk>  reacts with bases such as<unk>  hydroxide to form carbonates:<unk>  + NaOH →<unk>  + H2O Thermal decomposition At temperatures from 80–100 °C (176–212 °F),<unk>  gradually decomposes into<unk>  carbonate, water, and carbon dioxide. The conversion is faster at : : 2<unk>  →<unk>  + H2O + CO2 Most<unk> arbonates undergo this dehydration reaction. Further heating converts the carbonate into the oxide (above ): :<unk>  → Na2O + CO2 These conversions are relevant to the use of<unk>  as a fire-suppression agent ("BC powder") in some dry-powder fire extinguishers.
