Baking Soda Conversion: Cups to Grams

Baking soda (sodium bicarbonate) is a chemical leavening agent that reacts with acidic ingredients (buttermilk, vinegar, lemon juice, cocoa) to produce carbon dioxide bubbles, causing batters to rise. It is about 3–4 times stronger than baking powder and should be measured precisely.
