Answer 2

Answer:

Explanation:

Definition of acid:

Any hydrogen-containing material that has the ability to donate a proton (hydrogen ion) to another chemical is considered an acid.

Typically, sour tastes help to identify acidic chemicals. A fundamental definition of an acid is a molecule that has the ability to donate an H+ ion and maintain its energetic favorability even after losing H+. Acids are known to turn blue litmus paper crimson.

Definition of base:

A base is a molecule or ion that can take up an acid's hydrogen ion.

On the other hand, bases have a bitter flavour and a slick consistency. Alkali is the name for a base that can dissolve in water. Salts are produced when these compounds interact chemically with acids. Bases have a history of turning red litmus blue.

C6H5O a basic or an acid:

The basic phenoxide ion (C6H5O-) is weak.

Bronsted Lowry acid and base definition:

A base receives a proton from a Bronsted Lowry acid, H+.

A proton from an acid is taken up by a Bronsted Lowry base.

In this chemical equation, identify the Bronsted-Lowry acid and the Bronsted-Lowry base.

               NH2 + C6H5OH + C6H5O + NH3

Observe how the phenol, C6H5OH, transfers a proton to the base, NH2 in this acid-base process. As phenol: C6H5OH contributes a proton: H+, this reveals that phenol is acting as a Bronsted-Lowry acid.

Similar to this, the basic NH2 exhibits Bronsted-Lowry behaviour since it has accepted an H+ ion.

Given:

C6H5OH + NH2− → C6H5O− + NH3

Find:

NH2− is the

Consider:

The conjugate acid-base pairs in this equilibrium should be identified.

                                Water + NH2 = NH3 + OH-

As NH2- takes a proton, H+ from the reaction, it continues to function as a Lowry-Bronsted base.

H2O provides a proton to the molecule, serving as a Bronsted-Lowry acid so NH2- behaves like a base.

An acid-base pair that is conjugate is: NH2- and NH3.

Hence NH2- behaves like a acid or base according to the situation.
