Example of Brønsted – Lowry acid-base:

HCl (aq) + H2O (l) → Cl− (aq) + H3O + (aq)

When viewed with the Brønsted-Lowry theory, in the ionization reaction of HCl when dissolved in water, HCl acts as an acid and H2O as a base. The HCl turns into a Cl− ion after giving a proton (H +) to H2O. H2O accepts protons by using a pair of free electrons in the O atom to bind to H + to form hydronium ions (H3O +).

Examples of Lewis Acid Bases:

H ++ NH3 → NH4 +

Ion H + (Proton) is a Lewis Acid because it can accept Electron Pairs, while NH3 is a Lewis Base.

<h2>Further Explanation </h2>

Acid is a compound that makes a sour taste. A base may be a compound that reacts with acids.

The Brønsted – Lowry acid-base theory

The Brønsted-Lowry Theory is an acid-base reaction theory proposed separately by Johannes Nicolaus Brønsted and Thomas Martin Lowry in 1923. The basic concept of this theory is that when an acid and a base react with each other, acids will form their conjugate bases, and bases form their conjugate acids through proton exchange (hydrogen cations, or H +). This theory could be a generalization of the Arrhenius theory.

Lewis Acid-Base Theory

In 1923, G. N. Lewis proposed a broader acid-base theory compared to the two previous theories by emphasizing the electron pair associated with structure and bonding. According to the definition of Lewis acid-base:

acid is an electron pair acceptor.
bases are electron-pair donors.

There are many types of acid or bases. Based on the Bronsted-Lowry definition,

* A Bronsted-Lowry acid is a proton donor
* A Bronsted-Lowry base is a proton acceptor

Take this reaction for example:
HCl(aq)+ N<span>H</span>₃(aq)→N<span>H</span>⁴⁺(aq)+C<span>l</span>⁻(aq<span>)
</span>
HCl donates a proton, so it is a Bronsted-Lowry acid. Consequently, ammonia accepts this proton, so it is the Bronsted-Lowry base.

What is the molarity of a potassium triiodide solution, KI3(aq), if 30.00 mL of the solution is required to completely react wit

vfiekz [6]

Answer:

The molarity is 0.203 M

Explanation:

Using the formula C(oxi) x V(oxi) / [C(red) x V(red)] = N(oxi) / N(red)

Where oxi and red means reducing agent and oxidising agent respectively.

C = Concentration, V = Volume and N = number of moles.

C(oxi) = 0.5 M

V(oxi) = mL

C(red) = ?

V(red) = 30mL

Equation of reaction = 2K2S2O3 + KI3 = K2S4O6 + 3KI

so N(red) = 1 , N(oxi) = 2

from the equation above,

C(red) = 0.5 x 25 x 1 / (2 x 30)

= 0.203 M.

Which of the following reactions takes place with an increase in entropy under standard conditions?a. NH4(aq)+ CH3COO-(aq) ---&g

Elden [556K]

Answer:

a. NH4(aq)+ CH3COO-(aq) ---> NH3 (aq) +CH3COOH(aq)

Explanation:

Entropy -

In a system, the randomness is measured by the term entropy .

Randomness basically refers as a form of energy that can not be used for any work.

The change in entropy is given by amount heat per change in temperature.

When solid is converted to gas entropy increases,

As the molecules in solid state are tightly packed and has more force of attraction between the molecules, but as it is converted to gas, the force of attraction between the molecule decreases and hence entropy increases.

So,

The particles of the substance , if are tightly held by strong force of attraction will decrease the entropy ,

And

If the particles are loosely held , the entropy will increase .

When liquid is converted to solid entropy decreases,

As the molecules in liquid state are loosely packed and has less force of attraction between the molecules, but as it is converted to solid, the force of attraction between the molecule increases and hence entropy decreases.

Hence ,

The order of entropy is -

gas > aqueous > liquid > gas .

Hence, from the question ,

The reaction where there is increase in entropy is -

a. NH₄(aq)⁺ + CH₃COO⁻(aq) ---> NH₃ (aq) + CH₃COOH(aq)
