Question
which of these statements is true?
-if you add a strong acid or base to a buffer, the buffer's pKa or pKb will change
- To do calculations in which strong acid or base is added to a buffer, you only need to use the Henderson-Hasselbalch equation.
-If you add strong acid or base to a buffer, the pH will never change.
-Strong bases react with strong acids, but not with weak acids.
- To do calculations in which strong acid or base is added to a buffer, you need to calculate the amounts of substances from the neutralization reaction and then equilibrate.
Explanation / Answer
which of these statements is true?
-if you add a strong acid or base to a buffer, the buffer's pKa or pKb will change
The above statement is false because if we add a strong acid or base to a buffer, the buffer's pH will change not pKa or pKb will change.
- To do calculations in which strong acid or base is added to a buffer, you only need to use the Henderson-Hasselbalch equation.
This is false because we also need the number of moles of acids or base and volumes
-If you add strong acid or base to a buffer, the pH will never change.
The above statement is false because if we add a strong acid or base to a buffer, the buffer's pH will change not pKa or pKb will change.
-Strong bases react with strong acids, but not with weak acids.
The above statement is false because Strong bases react with strong acids as well weak acid also.
- To do calculations in which strong acid or base is added to a buffer, you need to calculate the amounts of substances from the neutralization reaction and then equilibrate.
The above statement is true.
