Which three statements accurately describe the blood buffering system in humans? the blood buffering system depends on the ionization of h2po–4 . the blood buffering system is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid, ionizing into bicarbonate and h+ . the blood buffering system utilizes the h2co3 / hco–3 conjugate acid/base pair. the blood buffering system utilizes the acetic acid/acetate conjugate acid/base pair. the blood buffering system maintains the ph of blood near 7.4.

The 3 statements that accurately describe the blood buffering system in humans are listed below.

Explanation:

1 The buffering system is facilitated by the enzyme carbonic anhydrase which inter converts carbon dioxide and water to carbonic acid ionizing into bicarbonate and H+.

2  The blood buffering system utilizes H2CO3/HCO3- conjugate acid base pair.Here Here H2CO3 is a conjugate acid whereas HCO3- is a conjugate base.

3 The blood buffering system maintain the pH of the blood near 7.4.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
