Answer: Option (B) is the correct answer.

Explanation:

It is known that acetic acid is a weak acid. Hence, it only ionizes partially into a solution.

Since, a solution consists of solute and solvent. A substance present in smaller quantity is known as solute and a substance present in larger quantity is known as solvent.

So, when we add more and more of a solute into a solvent then there will occur an increase in the concentration of solute. As a result, the solution becomes concentrated in nature.

Therefore, we can conclude that the given acid solution best be described as  weak and concentrated.

B because acetic acid is a weak acid and large quantity means you make it become concentrated

How the calculation of the [OH-], pH and % ionization for 0.619 M ammonia (NH3) NH3 + H2O (liq) rightwards harpoon over leftward
fomenos

Answer:

[OH⁻] = 3.34x10⁻³M; Percent ionization = 0.54%; pH = 11.52

Explanation:

Kb of the reaction:

NH3 + H2O(l) ⇄ NH4+ + OH-

Is:

Kb = 1.8x10⁻⁵ = [NH₄⁺] [OH⁻] / [NH₃]

<em>As all NH₄⁺ and OH⁻ comes from the same source we can write: </em>

<em>[NH₄⁺] = [OH⁻] = X</em>

<em>And as </em>[NH₃] = 0.619M

1.8x10⁻⁵ = [X] [X] / [0.619M]

1.11x10⁻⁵ = X²

3.34x10⁻³ = X = [NH₄⁺] = [OH⁻]

<h3>[OH⁻] = 3.34x10⁻³M</h3><h3 />

% ionization:

[NH₄⁺] / [NH₃] * 100 = 3.34x10⁻³M / 0.619M * 100 = 0.54%

pH:

As pOH = -log [OH-]

pOH = 2.48

pH = 14 - pOH

<h3>pH = 11.52</h3>
