The Short Answer
Baking powder is a mixture that contains a weak base (sodium bicarbonate, aka baking soda) and a weak acid (tartaric acid, for example). When moistened, the acid and base react to produce carbon dioxide gas, which gets trapped in the product being baked, making it fluffy. So why is baking soda a separate thing? Because sometimes whatever you're baking is already slightly acidic, and thus you need extra sodium bicarbonate to balance the inherent acids in the food being baked.
