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

Respuesta :

The concentration of acid before and after dissociation different in a concentrated solution of a strong acid .

Strong acids completely dissociate. Thus, after dissociation, the concentration will be different.

What are strong acids?



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

Strong acids have a higher pH than weak acids do at the same concentration. There are far fewer strong acids than weak ones. They are both present in lemon juice and regular vinegar (acetic acid) (citric acid).
