Question

A buffer can neutralize acid because: a. The weak acid grabs H* b. The conjugate base grabs H c. The buffer pH cannot be changed by any amount of acid d. Water grabs H and becomes neutral

Answer 1

Answer: Option (b) is the correct answer.

Step-by-step explanation:

A buffer is defined as a solution which does not lead to any change in pH of a solution upon addition of an acid or base.

For example,
`CH_(3)COOH \rightarrow CH_(3)COO^(-) + H^(+)`

Here,
`CH_(3)COOH` is the acid and
`CH_(3)COO^(-)` is its conjugate base.

So, when we add a conjugate base into an acid then it helps in neutralization of the solution.

Thus, we can conclude that a buffer can neutralize acid because the conjugate base grabs
`H^(+)` ion.
