How the basicity of boric acid is 1?
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. H3BO3 is a non protic (does not release H+) and mono basic (accepts one OH- ) acid .
How the N factor of borax is to?
The solution is as follows: Above is the structure of Borax. This clearly shows that each B is bonded to only 2 oxygen atoms, which indicated that each boron contributes 2 acidic protons. Thus, n factor is 2.
What is the value of boric acid?
Boric acid is a very weak acid with a pKa value of 9.2. At a lower pH than 7, boron is present in its nondissociated form (boric acid) and at a pH greater than 10.5, it is present in the dissociated borate form.
How do you find the N factor of H3BO3?
The net reaction is H3BO3 + 2H2O → [B (OH) 4] – + H3O+. Thus, one mole of H3BO3 in solution gives only one mole of H+, so its n-factor is 1.
Why is the basicity of Orthoboric acid one?
It does not lose 3H+ while it accepts one lone pair of electron from H2O .
What is the N factor of oxalic acid?
2
As oxalic acid has 2 moles of acidic H+ ions, which means one mole of oxalic acid can neutralize two moles of OH− . Hence, the n-factor of oxalic acid is 2 .
What is orthoboric acid used for?
Boric acid, also known as orthoboric acid, is a naturally occurring compound containing the element boron. It has been used in the U.S. since 1948 as a preventive control method for cockroaches, fleas, ants, and silverfish.
How is orthoboric acid prepared from borax?
(i) From borax: It may be prepared by adding an excess of sulphuric acid or hydrochloric acid to a hot saturated solution of borax. On cooling the reaction mixture, crystals of boric acid separate out. (iv) From boron halides: When boron halides are hydrolysed, orthoboric acid is formed.
What is the N factor of compounds?
The n-factor for such compounds is calculated by either the number of mole of electrons lost or gained by one mole of the compound because in such a case, n-factor of the compound acting as oxidizing agent or as reducing agent would be same.
What is the N factor of Orthoboric acid?
1
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.
What is the ‘n’ factor of boric acid?
– JEE Chemistry Q&A What is the ‘n’ factor of boric acid? Boric acid, H3BO3 is a monobasic weak acid it does not dissociate completely to give H+ ions Was this answer helpful?
What is the n-factor of H3BO3?
For an acid ‘n’ factor is the number of H+ ions replaced by 1 mole of an acid Boric acid, H3BO3 is a monobasic weak acid it does not dissociate completely to give H+ ions hence the ‘n’ factor of boric acid is 1 Was this answer helpful?
How do you use boric acid for eye infections?
Boric acid is the only acid in the world that is useful for eyes. It is mainly used for treating pinkeye or conjunctivitis, eye infections, and discharges from eyes. Dilute 1 tsp boric acid powder in half cup saline water or saline wash.
