How is baking soda a desiccant?

Baking soda (sodium bicarbonate) is not typically considered a desiccant, which is a substance that absorbs and holds moisture from its surroundings. Desiccants are commonly used to remove moisture from enclosed spaces to prevent spoilage or damage to sensitive items.

While baking soda has some moisture-absorbing properties, its primary use is as a leavening agent in baking and as a cleaning agent. It can help neutralize acids and remove stains, but it is not a primary choice as a desiccant due to its limited effectiveness compared to dedicated desiccants like silica gel or activated carbon.
