43.Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices:

(1) The total number of hydrogen atoms present in one molecule of an acid is the basis for classifying it as monoprotic, diprotic, triprotic, etc.

(2) In all Bronsted-Lowry acid-base reactions, the acidic species reacts with the basic species to produce water.

(3) A buffer is a solution that experiences zero change in pH when a small amount of acid or base is added to it.

a.All three statements are true.

b.Two of the three statements are true.

c.Only one of the statements is true.

d.None of the statements is true.

 

 

 

44.Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices:

(1) A Bronsted-Lowry base must contain an atom that can accept a proton.

(2) Both acidic and nonacidic hydrogen atoms may be present in an acid molecule.

(3) The molar hydronium ion concentration in a solution of pH 6.0 is 1 ? 10-6.

a.All three statements are true.

b.Two of the three statements are true.

c.Only one of the statements is true.

d.None of the statements is true.

(1) All rainfall, even in unpolluted areas, is acidic.

(2) Blood plasma, interstitial fluid, and intracellular fluid, the three general types of body fluids, all contain electrolytes.

(3) Blood plasma is slightly acidic because ions it contains undergo hydrolysis.

a.All three statements are true.

b.Two of the three statements are true.

c.Only one of the statements is true.

d.None of the statements is true.
