Sodium bicarbonate or sodium hydrogen carbonate is the chemical compound with the formula NaHCO3. Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder. It is capable of reacting chemically either as an acid or as a base (amphoteric). Furthermore, as it is relatively innocuous in most situations, there is no harm in using excess sodium bicarbonate.
