Baking soda, also called sodium bicarbonate, is a common baking ingredient, cleaner, deodorizer and pH regulator. It is commonly sold as a white powder that looks similar to baking powder.

Sodium Sodium is an alkali metal that bonds readily with other elements or ions.
Baking Soda. Baking soda is pure sodium bicarbonate. When baking soda is combined with moisture and an acidic ingredient (e.g., yogurt, chocolate, buttermilk, honey), the resulting chemical reaction produces bubbles of carbon dioxide that expand under oven temperatures, causing baked goods to rise.aking Soda.
