Regarding acids and bases:

A. Acids will increase the pH of a solution.
B. Acids will accept hydrogen ions in a solution.
C. Bases will decrease the pH of a solution.
D. Bases will accept hydrogen ions in a solution.



Answer :

Final answer:

Acids donate hydrogen ions to lower pH, while bases provide hydroxide ions to raise pH in a solution.


Explanation:

Acids are substances that provide hydrogen ions (H+) and lower pH, whereas bases provide hydroxide ions (OH-) and raise pH. The stronger the acid, the more readily it donates H+. For example, hydrochloric acid and lemon juice are very acidic and readily give up H+ when added to water. Conversely, bases are those substances that readily donate OH-. The OH- ions combine with H+ to produce water, which raises a substance's pH. Sodium hydroxide and many household cleaners are very alkaline and give up OH- rapidly when placed in water, thereby raising the pH.
