What is "bicarbonate of soda"?

Bicarbonate of soda, also known as baking soda, is a versatile white powder commonly used in cooking, cleaning, and personal care. In cooking, it acts as a leavening agent, causing baked goods to rise by producing carbon dioxide gas when mixed with acidic ingredients. This gas creates bubbles in the batter or dough, causing it to rise and become light and fluffy during baking. Its alkaline properties make it effective for removing odors and cleaning surfaces, from scrubbing pots and pans to freshening carpets. Additionally, bicarbonate of soda can be used as a gentle exfoliant in skincare routines, helping to remove dead skin cells and balance pH levels.
