How baking soda differs from baking powder
Baking soda is sodium bicarbonate alone, and baking powder already includes a dry acid.

From the opening
Baking soda is sodium bicarbonate, and it releases carbon dioxide when an acid meets it in a moist batter. Baking powder is that bicarbonate already blended with a dry acid and some starch, so the acid does not have to come from the rest of the recipe. The opening covers why soda needs an acid partner, what the powder already includes, and how double-acting powder is timed.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
