Question

Human blood has a pH of 7.4. How do buffers in the blood affect the pH?


A. Buffers are acids that cause the pH of blood to decrease.

B. Buffers are bases that cause the pH of blood to increase.

C. Buffers prevent small amounts of acid or base from changing the pH of blood.

D. Buffers are catalysts that prevent chemical reactions from changing the pH of blood.

Answer 1

Answer:

C

I think buffers prevents small amounts of acids and blood from coming and changing the pH of the body, because the buffers are barriers that do not let blood and acid pass through.

Hope it helps!

Answer 2

Buffers basically prevent tiny amounts of whether acid or base from changing the pH of blood. The correct option is C.

What are buffer?

A buffer is a solution that can withstand changes in pH caused by the inclusion of acidic or basic constituents.

It can subdue minimal quantities of added acid or base, allowing the pH of the solution to remain reasonably constant.

Buffers sustain a modest pH by disarming any additional acid or base, trying to make them a weaker acid or base.

Consider a buffer composed of the weak base ammonia, NH3, and its conjugate acid, NH4+.

Our body's three key buffer systems are the carbonic acid bicarbonate buffer system, the phosphate buffer system, and the protein buffer system.

Thus, the correct option is C.
