Answer: Option (B) is the correct answer.
Step-by-step 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.
