Sodium bicarbonate - Common Organic Chemistry

Sodium bicarbonate (NaHCO3) is commonly referred to as baking soda by people outside of chemistry. It is amphoteric, meaning it can neutralize both acids and bases. The most common use of NaHCO3 is as a saturated aqueous solution for performing a basic wash during an aqueous workup.
