What are sour salts?

salts are formed by the reaction of acid and base, known as neutralizing reactions. Acids can be monoprotic, diprotic, or polyprothostic, which means that the acid molecule can donate one, two or more protons when it reacts with the basic molecule - protons usually take the form of hydrogen ion (H

+). Monoprotic acids such as hydrochloric acid (HCI) and nitric acid (HNO 3 ) can form only one type of salt, chlorides and nitrates, but digratic and polyprotic acids can form more than one. For example, sulfuric acid (H _{2 so 4 ) is diplotic because it can donate one or two ions h ^{+ and can consist of two series of salts, sulfur and sulphates. Where acid is given less than the maximum number of protons available in the reaction, this is called partial neutralization and the result is acidic salt.}}

If sulfuric acid is neutralized for the first time, a dium sulfide is formed: h _{2 so 4 + NaOH -> NAHSO 4 + H 2 O. If more sodium hydroxide is added, neutral sodium sulfate is formed: NaSO 4 + Naoh -> on 2 Orthophosphorn (H 3 after 4 ) is tritrotic and therefore consists of three series of salts: dihydrogen phosphate, hydrogen phosphates and phosphates, the first two of which are acidic salts.}

acid salts are not necessarily acidic. Sodium sodium carbonate (nahco _{3 ) or sodium bicarbonate, can be considered as acidic acid salt - weak diplotic acid - and sodium hydroxide - and can be prepared by carbon dioxide (Korejmba sodium: 2NAOH + what 2 -> on 2 3 3 + h 2 Sodium to form sodium carhoganate: at 2 3 + what 2 + h 2 o -> 2NAHCO 3 . This acidic salt is slightly alkaline in the solution, since HCO 3 - anions form carbonate (H 2 3 ) and hydroxyl ions (oh}

- ) in water in water.

There are many applications for sour salts. The use of sodium or "baking soda" bicarbonate as an increased reagent when baking is well known; Weak acids easily respond to the release of carbon dioxide gas and form bubbles in a cake mixture. The sodium sodium sodium, also called sodium bisulphate, forms a strongly acidic solution in the water and is sometimes used as a substitute for sulfuric acid for various purposes, such as completing metals, reducing pH in pools and in children's chemical sets. Acidal salts, especially hydrogen phosphated dihydrogen phosphates are also widely used in buffer solutions.
