The Ionic Product of Water K_w is the equilibrium constant for the reaction in which water undergoes an acid-base reaction with itself. That is, water behaves simultaneously as both an acid and a base. At 298 K, the value of K_w is 1 x 10^-¹⁴ mol² dm^-⁶.

The substance which can accept the electron pair donated by the Lewis base, they are termed as Lewis acid.
is a compound which is made up of two atoms namely boron and fluorine.
The atomic number of boron is 5 and its electronic setup is 2, 3. Its valency is 3 and Flourine (2,7) valency is 1.
Consequently, by imparting 1 electron to every fluorine molecule, boron has 3 sigma bonds around it which means that each boron atom is surrounded by 6 electrons.
To have the steady octet setup Boron needs 2 additional electrons.
Since boron can accept a couple of electrons from Lewis base, it is considered as Lewis acid.

Is boric acid a protic acid? Explain

Posted by Vaibhav Tyagi 6 years ago

CBSE > Class 11 > Chemistry

1 answers

Gaurav Seth 6 years ago

As you know, protic acid give proton in water , it is not a protic acid because it doesn't ionize in H2O to give a proton . it acts as Lewis acid by accepting electrons from a hydroxyl ion of water and in turn releases H+ ions.
e.g., B(OH)3 + HOH ----> [B(OH)4]- + H+
