A strong acid:Group of answer choiceshas a higher pH than a weak acid of the same concentrationrequires fewer moles to neutralize a strong base than a weak acid doeshas a stronger conjugate base than a weak acidproduces a higher concentration of its conjugate base than a weak acid does
Solution 1
A strong acid:
-
Has a lower pH than a weak acid of the same concentration: The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic and a pH greater than 7 is basic. Strong acids are more acidic than weak acids, so they have a lower pH.

Requires fewer
Solution 2
A strong acid:
-
Has a lower pH than a weak acid of the same concentration: The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic and a pH greater than 7 is basic. Strong acids are more acidic than weak acids, so they have a lower pH.
-
Requires fewer moles to neutralize a strong base than a weak acid does: This is because strong acids completely ionize in solution, meaning they donate more H+ ions to the solution than weak acids. These H+ ions can react with OH- ions from a base to form water, neutralizing the acid.
-
Has a weaker conjugate base than a weak acid: The strength of an acid is inversely proportional to the strength of its conjugate base. So, a strong acid has a weak conjugate base.
-
Produces a higher concentration of its conjugate base than a weak acid does: This is not true. A strong acid completely ionizes in solution, meaning it donates all its H+ ions to the solution and leaves behind the conjugate base. However, because the conjugate base of a strong acid is weak, it does not readily accept H+ ions to become the acid again. Therefore, the concentration of the conjugate base in solution is not higher for a strong acid than for a weak acid.
