If you need to substitute baking soda in place of baking powder, you will need to add an acid to the recipe in order to help the baking soda have the proper chemical reaction. Instant feedback tells you whether you're right or wrong and helps you learn quickly by explaining why . In the case of sodium bicarbonate reacting with sodium hydroxide, hydrogen ions formed by the dissociation of bicarbonate are removed by reaction with hydroxide ions to form water, causing the equilibrium to shift to favor greater dissociation of bicarbonate, driving the reaction to completion.
