ANSWER:

Problem 15.125

Consider a buffered solution containing . Which of the following statements concerning this solution is(are) true? .

a. A solution consisting of would have a higher buffering capacity than one containing .

b. If , then the pH is larger than the value.

c. Adding more to the initial buffer solution will decrease the pH.

d. If , then pH 3.36.

e. If , then pH = 10.64.

Step by step solution

Step 1 of 5

(a) Statement-A solution consisting of and would have a higher buffering capacity that one containing .

No, the buffering capacity does not depend on the quantity of the component of the buffer solution depending on the amount of present.

Thus, this statement is not true.
