QUESTION 51 Buffer capacity is best defined as: OA) Buffer capacity is the amount of acid or base that can be added to a buffer
without destroying its effectivene OB) Buffer capacity is the amount of acid that can be added until all of the base is used up O C) Buffer capacity is the amount of base that can be added until all of the acid is used up OD) Buffer capacity is the amount of acid that can be added until all of the acid is used up O E) Butter capacity is the amount of base that can be added until all of the base is used up QUESTION 52 Which of the following acids (listed with Ka values) and their conjugate base would form a buffer with a pH of 2 94? A)HC7H502. Ka = 65 x 10-5 OB) HF ka 9.9 10-4 OC) HCIO. Ka = 2.9 * 10-8 DHCN. K = 49 10-10 E) HCIO2. K - 41 10-2 Click Save and Submit to save and submit. Click Save AT Answers to see all ans .
The best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"
Explanation:
A buffer is a solution that is somewhat resist to pH changes by reacting with acids and bases that may be added into the solution. It's capacity is the amounto of acid or base that can be added into solution without much change in pH.
So the best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"
The swimming pools pH is below 7, meaning it is slightly acidic. If you want to make the pH higher, you must add a base which by definition has a pH higher than 7.
