What is the basicity of H3BO3 acid?

Answer: Explanation:H3BO3 is boric acid. Boric acid dissociates weakely in water, but it is acidic due to its interaction with water to form tetrahydoxyborate ion. it is monobasic Lewis acid of boron, its basicity is 1, because it has capacity to give 1 H+ ion.

What is n factor of H3BO3?

1
Here, boron acts as a Lewis acid because it is an electron-deficient species. Boric acid may be a monobasic weak acid; it doesn’t dissociate completely to offer Hydrogen ions therefore, the ‘n’ factor of boric acid is 1.

Is H3BO3 a strong base?

Boric acid is a weak acid, with pKa (the pH at which buffering is strongest because the free acid and borate ion are in equal concentrations) of 9.24 in pure water at 25 °C.

Is H3BO3 acidic basic or neutral?

An aqueous solution of boric acid is acidic. Lewis acid accepts electron from other entities. Here, it’s important to keep in mind is that boric acid (H3BO3) doesn’t dissociate in water to give H+ ions. Rather it accepts OH- ion from water to form H4BO4-.

What is the basicity of H 3 PO 2?

H3PO2 has one ionizable –OH group, thus its basicity is 1.

Why is H3BO3 not Arrhenius?

The chemical formula of boric is H3BO3 also written as B(OH)3. This weak boric acid accepts hydroxyl ion from the water, It does not dissociate to give hydrogen ion or hydronium ion i.e. H3O+. Hence it is not Arrhenius acid.

What are n factor of H3BO3 and H3PO3 respectively?

n-factor of H3PO3 = 1 or 2 because one of the H is not replaceable in H3PO3. This can be seen using its structure . The H atoms which are linked to oxygen are replaceable while the H atom linked directly to central atom (P) is nonreplaceable. The net reaction is H3BO3 + 2H2O ® [B(OH)4]– + H3O+.

How many different elements are in boric acid H3BO3?

Boric Acid is a monobasic Lewis acid with the chemical formula H3BO3. It is an acid-containing four atoms of oxygen, one atom of phosphorus, and three atoms of hydrogen.

Is H3BO3 a Lewis base?

monobasic and weak Lewis acid.

Why is H3BO3 a weak Lewis acid?

Central boron atom in H3BO3 is electron deficient, therefore it accepts a pair of electron, hence it is weak Lewis acid. There is no d-orbital of suitable energy in boron atom. So, it can accommodate only one additional electron pair in its outermost shell. Thus, H3BO3 is a monobasic weak Lewis acid.

What is the structure of H3BO3?

Boric acid/Formula

How does H3BO3 ionize in water?

It ionizes in water as. B(OH)3​+H2​O⇌B(OH)4−​+H+;Ka​=5.
