Question

In each of the following cases, is the concentration of acid before and after dissociation nearly the same or very different? Explain your reasoning: (b) a concentrated solution of a weak acid;

Answer 1

Weak acids partially dissociate, they dissociate to a small intent. So after dissociation, the concentration will not have much significant difference.

What are weak acids?

A weak acid is one that partially separates into its ions in water or an aqueous solution. On the other hand, when strong acids are in water, they completely separate into their ions. The conjugate base of a weak acid is also a weak base, and vice versa holds true for the conjugate acid of a weak base.

At the same concentration, weak acids have a lower pH than strong acids. Strong acids are far less common than weak ones. Lemon juice and common vinegar (acetic acid) both include them (citric acid).
