Acids, Bases, Salts, Buffers Flashcards
(6 cards)
1
Q
Buffer
A
Solutions that resist a change in pH when small amounts of acid or base are added
2
Q
What is a buffer made of?
A
A weak acid and its salt or a weak base and its salt
3
Q
When is a buffer the best?
A
When the ratio of acid to salt or base to salt are close to 1
4
Q
Henderson-Hasselbalch Equation
A
pH = pKa + log([B]/[A])
Used only when there is a buffer solution present in order to calculate pH
5
Q
Equivalence point
A
moles of acid = moles of base
6
