Why is it called monobasic acid?
Basicity of an acid is the number of hydronium ions formed by one molecule of the acid in its aq. solution. A monobasic acid has only one hydrogen ion to donate to a base in an acid-base reaction. Hence, a monobasic molecule has solely one replaceable hydrogen atom.
What is the definition of monobasic acid?
Definition of monobasic of an acid. : having only one replaceable hydrogen atom.
Which acid is monobasic acid?
Monobasic acids are acids that can replace or lose only one hydrogen atom. Some of the examples of monobasic acids are nitric acid, hydrochloric acid and periodic acid. It is a weak monobasic acid, it can accept one hydroxide ion from a water molecule, when water is added to boric acid.
Why is boric acid a weak Lewis acid?
A) monobasic and weak lewis acid. B) Similarly, an acid is tribasic if it contains three hydrogen ions for donation. …
How Boric acid is monobasic?
– Although Boric acid contains 3 OH groups yet it can act as monobasic acid rather than tribasic acid. This is because it does not act as a proton donor rather it accepts a pair of electrons from OH- ions. – Since, only one \[{{H}^{+}}\]can be released by a water molecule, boric acid is a monobasic acid.
Is Ethanoic acid monobasic?
Acetic acid has 4 hydrogen atoms in its molecule but is a monobasic acid.
Why is hno3 monobasic?
Nitric acid contains one replaceable hydrogen atom. Hence, it is a monobasic acid.
Is perchloric acid a binary acid?
Simple acids, known as binary acids, have only one anion and one hydrogen. Therefore, HClO4 is called perchloric acid. With one fewer oxygen than the “-ate” ion, the acid will have the suffix “-ous.” For example, chlorous acid is HClO2.
What is the function of boric acid?
Boric acid is often used as an antiseptic, insecticide, flame retardant, neutron absorber, or precursor to other chemical compounds. It has the chemical formula H3BO3 (sometimes written B(OH)3), and exists in the form of colorless crystals or a white powder that dissolves in water.
Why is nitric acid monobasic?
Basicity of an acid is defined as the number of replaceable hydrogen atoms present in a molecule of an acid. So, a monobasic acid is an acid which contains one replaceable H+ ion. Nitric acid contains one replaceable hydrogen atom. Hence, it is a monobasic acid.
Why does boric acid act as monobasic acid instead of tribasic?
Although Boric acid contains 3 OH groups yet it can act as monobasic acid rather than tribasic acid. This is because boric acid does not act as proton donor rather it accepts a pair of electrons from OH- ions. It does not dissociate to produce ions rather forms metaborate ion and in turn release ions.
Why is boric acid considered a weak acid?
Although Boric acid contains 3 OH groups yet it can act as monobasic acid rather than tribasic acid. This is because boric acid does not act as proton donor rather it accepts a pair of electrons from OH- ions. It does not dissociate to produce ions rather forms metaborate ion and in turn release ions. Hence boric acid is considered a weak acid.
Why does boric acid behave as Lewis acid but not proton donor?
Because boric acid does not act as proton donor but it accepts a lone pair of electrons from OH − ions and forms B(OH)4 −. Boric acid behaves as Lewis acid because it accepts a lone pair of electrons from OH − ions from water.
