Verified
Human blood has a pH of 7.4; therefore, it can be classified as a ________.
A) weak acid
B) strong base
C) strong acid
D) neutral solution
E) weak base
Weak Base
A base that partially dissociates into its ions in an aqueous solution, resulting in a weakly alkaline solution, as opposed to a strong base which fully dissociates.
Strong Base
A substance that can readily accept hydrogen ions and is completely or nearly completely dissociated in aqueous solution, resulting in a high pH.
- Appreciate the fundamentals of the pH scale and its relevance, with a particular emphasis on the involvement of hydrogen (H+) and hydroxide (OH-) ions in identifying the acidic or alkaline nature of a solution.
- Recognize the importance of pH in biological systems and how it affects cellular function.

Final Answer :
E
Explanation :
Human blood has a pH slightly above 7, which classifies it as a weak base. A pH of 7 is neutral, so anything above 7 is basic (alkaline), and below 7 is acidic.
