Answer:
Non of these are true
Explanation:
To form a solution, solute-solvent interaction must exceed solute-solute and solvent-solvent interaction. Hence a new attraction leading to solvation of the solid in the solvent is set up.
Answer:
Dissociated state is the predominant one
Explanation:
When a molecule with pKa of 4.52 is in an aqueous solution at pH = 4.0, follows the H-H equation, thus:
pH = pKa + log₁₀ [A⁻] / [HA]
<em>Where [A⁻] is the dissociated state and [HA] represents the protonated state</em>
Replacing:
4.0 = 5.2 + log₁₀ [A⁻] / [HA]
-1.2 = log₁₀ [A⁻] / [HA]
0.063 = [A⁻] / [HA]
[HA] = 16 [A⁻]
That means you have 16 times more [HA] than [A⁻] and the <em>dissociated state is the predominant one</em>
