Ammonium bicarbonate, also called bicarbonate of ammonia, ammonium hydrogen carbonate, hartshorn, or powdered baking ammonia, is the bicarbonate salt of ammonia. In Chemistry, the standard state of a material is its state at 1 bar (100 Kilopascals exactly In Inorganic chemistry, bicarbonate ( IUPAC -recommended nomenclature hydrogencarbonate) is an intermediate form in the Deprotonation Salt is a Dietary mineral composed primarily of Sodium chloride that is essential for Animal life but toxic to most land plants Ammonia is a compound with the formula N[[hydrogen H3]] It is normally encountered as a Gas with a characteristic pungent Odor

Ammonium bicarbonate is formed as shown below, or by passing carbon dioxide through a solution of the normal compound, when it is deposited as a white powder, which has no smell and is only slightly soluble in water. Carbon dioxide ( Chemical formula:) is a Chemical compound composed of two Oxygen Atoms covalently bonded to a single The aqueous solution of this salt liberates carbon dioxide on exposure to air or on heating, and becomes alkaline in reaction. In Chemistry, an alkali (from Arabic: Al-Qaly القلي القالي) is a basic, ionic salt of an Alkali metal The aqueous solutions of all the carbonates when boiled undergo decomposition with liberation of carbon dioxide and the substance with which the carbonate ion reacted to form the bicarbonate, in this case, ammonia:

NH₄HCO₃ → NH₃ + H₂O + CO₂

Properties

At room temperature ammonium bicarbonate is a white, crystalline powder with a slight odour of ammonia that can dissolve in water to give a mildly alkaline solution. Water is a common Chemical substance that is essential for the survival of all known forms of Life. In Chemistry, an alkali (from Arabic: Al-Qaly القلي القالي) is a basic, ionic salt of an Alkali metal In Chemistry, a solution is a Homogeneous Mixture composed of two or more substances It is however insoluble in acetone and alcohols. Acetone (also known as propanone, dimethyl ketone, 2-propanone, propan-2-one and β-ketopropane) is a colorless mobile flammable In Chemistry, an alcohol is any Organic compound in which a Hydroxyl group ( - O[[hydrogen H]]) is bound to a Carbon Ammonium bicarbonate decomposes at 36 to 60 °C into ammonia, carbon dioxide and water vapor in an endothermic process (as it is with many ammonium salts) and so causes a drop in the temperature of the water. Ammonia is a compound with the formula N[[hydrogen H3]] It is normally encountered as a Gas with a characteristic pungent Odor Carbon dioxide ( Chemical formula:) is a Chemical compound composed of two Oxygen Atoms covalently bonded to a single In Thermodynamics, the word endothermic "within-heating" describes a process or reaction that absorbs Energy in the form of Heat. Ammonium is also an old name for the Siwa Oasis in western Egypt. When reacted with acids carbon dioxide is produced, while reactions with alkalis give ammonia. In Computer science, ACID ( Atomicity Consistency Isolation Durability) is a set of properties that guarantee that Database transactions are

Uses

Ammonium bicarbonate was used in the food industry as a raising agent (e. A leavening agent (sometimes called just leavening or leaven) is a substance used in Doughs and batters that causes a foaming action intended g. , for gingerbread or Chinese youtiao) before the introduction of baking soda. Gingerbread is a sweet that can take the form of a Cake or a Cookie in which the predominant flavors are ginger and raw Sugar. Youtiao, you char kway, or yau ja gwai, sometimes known in English as Chinese cruller or fried bread stick, Sodium bicarbonate or sodium hydrogen carbonate is the Chemical compound with the formula NaHCO3 Ammonium bicarbonate is still used in many food products, in addition to baking soda. Many baking cookbooks (especially from Scandinavian countries) may still refer to it as hartshorn or hornsalt ^[1]^[2]. It is fine to replace it with baking soda. ^[3]

It is commonly used as an inexpensive nitrogen fertilizer in China, but is now being phased out in favor of urea because of its relatively low quality and instability. Fertilizers ( also spelt fertiliser are chemical compounds given to Plants to promote growth they are usually applied either through the soil for uptake by plant Urea is an Organic compound with the Chemical formula ( N[[hydrogen H]]22 C[[oxygen O]] This compound is used as a component in the production of fire-extinguishing compounds, pharmaceuticals, dyes, pigments and it is also a basic fertilizer being a source of ammonia. A dye can generally be described as a Colored substance that has an affinity to the substrate to which it is being applied Ammonium bicarbonate is still widely used in the plastic and rubber industry, in the manufacture of ceramics, in chrome leather tanning and for the synthesis of catalysts. The word ceramic is derived from the Greek word κεραμικός ( keramikos) Tanning is the process of converting Putrescible skin into non-putrescible Leather, usually with Tannin, an Acidic Chemical compound Catalysis is the process in which the rate of a Chemical reaction is increased by means of a Chemical substance known as a catalyst

Safety

Ammonium bicarbonate is an irritant to the skin, eyes and respiratory system. The skin is the outer covering of living tissue of an animal (or plant Eyes are organs that detect Light, and send signals along the Optic nerve to the visual areas of the brain In living organisms a respiratory system functions to allow Gas exchange. Additionally, the acrylamide that is formed during the baking process has been connected to cancer in lab animals. The Chemical compound acrylamide (acrylic Amide) has the Chemical formula C 3 H 5 N[[Oxygen O]]
