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.
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 ...
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 Originally made from ground deer horn and called hartshorn, today it is called baker's ammonia.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]

But you can make your own baking powder: combine 2 tablespoons of baking soda with 1/4 cup of cream of tartar and pass it several times through a sifter. Some cooks believe the DIY baking powder ...
Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire.
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.
