Hi Weak Or Strong Acid

Is Hydrogen iodide (Hullo) an acid or base? Strong or Weak - Conjugate base

Hydrogen iodide belongs to the hydrogen halide family consist of one iodine and one hydrogen with the chemical formula HI. Information technology appears equally a colorless gas with a pungent aroma. Exposure to this gas can cause strong irritation in the peel, eyes, etc.

In this commodity, we will talk over Is Hydrogen iodide (Howdy) is an acid or base of operations? Its nature(Potent or weak).

So, Is Hi an acrid or base of operations? HI is considered an acid. Information technology releases H⁺ ions when dissolved in an aqueous solution. And acid is a substance that donates the proton to other compounds or release H⁺ ions in a water solution. Therefore, HI is acid, since, it releases H⁺ ions in a water solution.

Why Howdy is an acrid?

To Know Why HI is acting as an acrid? We have to look into the famous theory given past Arrhenius for the acid compounds.

This theory land that a compound is said to be acid when it produces H⁺ ions on dissolving in an aqueous solution and forms H ₃ O ⁺ ions when combining with the water molecule.

Now have a expect at HI dissociation in an aqueous solution.

⇒ How-do-you-do → H⁺ + I^–

As on dissolving Hi in an aqueous solution, it dissociates in two ions H⁺ and I^–. So, a proton ion(H⁺) combines with a h2o molecule and forms H _iii O ⁺ .

⇒ HI _{( g )} + H _ii O _{( l )} → H _three O ⁺ _{( a q )} + I ⁻ _{( a q )}

Also, Arrhenius sate that an acid is a chemical compound that increases the concentration of hydrogen ion(H⁺) in solution.

In the case of the HI compound, when dissolved in an aqueous solution it liberates the H⁺ ions, hence increases the concentration of hydrogen ion in the final solution.

So, the Hullo compound definitely following all conditions needs to meet for the Arrhenius acid compound. Hence, we tin say the How-do-you-do is an Arrhenius acid compound.

Now we wait for another most important acid-base theory that is the Bronsted-Lowry theory.

This theory states a compound is classified as an acrid when it donates the proton to other species and itself forms a conjugate base of operations. And a compound is classified as a base when it accepts the proton from other species and itself forms a conjugate acid.

In short as per Bronsted-Lowry theory–

A Bronsted-Lowry acrid is a proton (hydrogen ion) donor.
A Bronsted-Lowry base is a proton (hydrogen ion) acceptor.

Let's check whether How-do-you-do fulfills the requirement for classifying as Bronsted-Lowry acid or not.

Consider the reaction of Hi reacting with NH₃.

Here, Hello reacts with ammonia and donates the proton which is accepted by NH₃ and itself forms an I^– conjugate base.

Illustration of above reaction (HI with NH₃):-

How-do-you-do human activity as Bronsted-Lowry acid as it donates the proton and forms a conjugate base.
NH3 acts as a Bronsted-Lowry base of operations equally it accepts the proton from HI and forms a Cohabit acid.
Ammonium ion (NH_four ⁺) is the conjugate acid of the base NH₃.
Iodine ion(I^–) is the conjugate base of the acid HI.

Is Hydroiodic (Hi) strong acid or weak acid?

A strong acrid is something that completely dissociates or is 100% ionized in a solution. Some examples of strong acrid – HCl, HBr, HNO_three, H₂SO₄, etc.

Is H2SO4 a potent acid?
Is HNO3 a strong acrid?
Is HCl a strong acrid?
Is HBr a stiff acid?
Is HClO4 a potent acrid?

Characteristics of strong acrid:-

They are strong electrolytes and have high conductivity.
Their pH value lies between ane to 3.
They dissociate completely and release a large number of H⁺ ions in a solution.

A weak acid is something that is non able to dissociate completely or partially dissociate in a solution. Some examples of a weak acids – are CH_iiiCOOH, H₃PO₄, HF, NH₄ ⁺, etc.

Besides, Read :-

Is CH3COOH a weak acrid?
Is HF a weak acid?
Is HCN a weak acid?
Is HNO2 a weak acid?
Is HCOOH a weak acid?
Is H3PO4 a weak acrid?
Is H2CO3 a weak acid?
Is NH4+ a weak acid?

Characteristics of Weak acids:-

They are weak electrolytes and have less electrical conductivity as compared to strong acids.
Their pH value lies between 3 to 7.
They ionized partially to produce H⁺ in a solution.

Now, Is How-do-you-do a strong or weak acrid? HI is a strong acid. Because it readily dissociates in an aqueous solution, which means no undissociated parts of information technology remain in the solution, all parts completely break off and are ionized in an aqueous solution.

Why Hi easily breaks off and dissociate readily in an aqueous solution?

Howdy can easily pause off because the bond forcefulness of the H-I bond is very weak due to the large gap in the orbital size of these ions. As the orbital size for H is 1s and for I atom, it is 5p.

Hence, overlapping of 1s and 5p orbital becomes very small-scale, this causes bounden between H-I very weak in nature, hence the covalent bond in H-I cantlet easily breaks off and makes it readily dissociate in aqueous to liberate H⁺ ion.

More than reasons, why How-do-you-do acts as strong acid?

Every bit we know, element of group vii atoms take very high electronegativity and a high free energy level, these make a halogen atom size bigger and hydrogen is just reverse to information technology. Then, the allure between iodine and hydrogen becomes very weak.

Therefore, Hydrogen easily breaks off from How-do-you-do due to its modest size and causes Hullo to readily dissociates in an aqueous solution and completely splits into two ions (H⁺ and I^–).

What is the conjugate base of operations of Howdy?

Whenever the acrid donates the proton, it converts into the conjugate base of operations and whenever the base accepts the proton, it converts into the conjugate acrid.

Conjugate acid is an acrid that formed when the base chemical compound gains one proton and the conjugate base is a base that formed when the acid compound loses one proton.

The concept of cohabit acid-base pair.

A very strong acrid ever forms a weak conjugate base.
A very strong base always forms a weak conjugate acid.
A very weak acrid ever forms a strong cohabit base.
A very weak base always forms a potent conjugate acid.

As per Bronsted-Lowry, HI is acrid and loses one proton when combines with the water molecule and forms a base known as the cohabit base of an acid(Howdy).

∴ The conjugate base of operations of Howdy is I^–.

Is HI Lewis acid or base?

When the chemical compound accepts the pair of electrons from another compound classified as Lewis acid and when the chemical compound donates the pair of electrons to another chemical compound classified as Lewis base.

⇒ Lewis acid → electron pair acceptor

⇒ Lewis base → electron pair donator

At present, Is HI Lewis acrid or base? Definitely, HI is a lewis acid. Because it accepts one alone pair when combined with a water molecule, forming hydronium ion and I^– conjugate base.

As iodine is more electronegative than hydrogen and has iii solitary pair around it, being more than electronegative it concenter more than electron towards itself, hence a negative charge induces an iodine atom and a positive charge on the hydrogen cantlet.

The lonely pair on the water molecule(H₂O) attracted slightly to the hydrogen cantlet, also more electrons repelled towards the iodine atom due to its negative charge.

Furthermore, a coordinate bond formed between oxygen and hydrogen, and the iodine breaks away as an iodide ion.

So, the whole HI molecule acts every bit lewis acid as it accepts the pair of electrons from H_iiO, and in this process, the iodide ion breaks off.
