Baking powder is a dry chemical leavening agent, a mixture of a carbonate or bicarbonate and a weak acid. The base and acid are prevented from reacting prematurely by the inclusion of a buffer such as cornstarch. Baking powder is used to increase the volume and lighten the texture of baked goods.
Ammonium bicarbonate decomposes above about 36 °C into ammonia, carbon dioxide, and water in an endothermic process and so causes a drop in the temperature of the water: NH 4 HCO 3 → NH 3 + H 2 O + CO 2. When treated with acids, ammonium salts are also produced: NH 4 HCO 3 + HCl → NH 4 Cl + CO 2 + H 2 O. Reaction with base produces ammonia.
It was the precursor to today's more commonly used baking powder. Originally made from ground deer horn and called hartshorn, today it is called baker's ammonia. It is prepared by the sublimation of a mixture of ammonium sulfate and calcium carbonate and occurs as a white powder or a hard, white or translucent mass. [4]
To use baking powder when baking soda is called for: Simply use 3 times the amount of baking powder. So if your recipe calls for 1 teaspoon baking soda so you would need 3 teaspoons of baking powder.

Baking soda is simpler than baking powder. It only contains one ingredient: sodium bicarbonate. The naturally alkaline compound works by interacting with acidic substances.
Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −
Oil of hartshorn is a crude chemical product obtained from the destructive distillation of deer antlers. Salt of hartshorn refers to ammonium carbonate, an early form of smelling salts and baking powder obtained by dry distillation of oil of hartshorn. Spirit of hartshorn (or spirits of hartshorn) is an archaic name for aqueous ammonia ...
