Arrhenius’s Theory of Acid and Base
What is acid, what is base, and what is the difference between acid and base? these questions are nightmares to chemists in the early 15 and 16 centuries. To solve these questions a chemist name Arrhenius came up with a theory called Arrhenius theory. According to Arrhenius’s theory, a substance that gives H+ ion in its aqueous solution is called acid whereas the substance that ionizes OH– ion in the aqueous solution is called a Base.
HCl(aquaous solution) ⇌ H+ + Cl–
NaOH(aquaous solution) ⇌ Na+ + OH–
Bronsted-Lowry Theory of Acid and Base
Bronsted-Lowry Theory also provides an explanation of acid and base, according to this theory, acid is an H+ ion or a proton donor and it forms its conjugate base whereas the base is a substance that accepts an H+ ion or a proton to form conjugate acid.
Bronsted-Lowry Acid
According to Bronsted-Lowry acids are substances that donate a proton or H+ ion to the other compound.
Acid ⇌ Proton + Conjugate Base
Example: H2SO4 ⇌ H+ + HSO4–
Bronsted-Lowry Base
According to Bronsted-Lowry bases are substances that accept a proton or H+ ion from other compounds.
Base + Proton ⇌ Conjugate Acid
Example: OH– + H+ ⇌ H2O
Acids, Bases and Salts
Acids, Bases, and Salts are the main chemical compounds that exist in our surroundings. Acids, Bases, and Salts are compounds that occur naturally and can also be created artificially. They are found in various substances including our food. Vinegar or acetic acid is used as a food preservative. Citrus fruits have citric acid and etc.
Other than food they also have a wide variety of uses such as in various industries, manufacturing plants, processing plants, laboratories, and others. In this article, we will learn about Acids, Bases, and Salts, their properties, types, uses, and others in detail. The image given below shows acid and base which when reacting form salt.
