Buffers

Question 1

Buffer solution

Answer 1

A solution of a weak acid and its salt, or a weak base and its salt. The solution has the ability to resist changes in pH upon the addition of small amounts of either acid or base, or when the solution is diluted

Question 2

Acid buffer

Answer 2

The mixture of a weak acid and it’s conjugate base

Question 3

Basic buffer

Answer 3

Mixture of a weak base and it’s conjugate acid

Question 4

Henderson - hasselbalch equation

Answer 4

Used to approximate the pH of a buffer solution

Question 5

Buffer action

Answer 5

Property of resisting the change in pH

Question 6

Buffer capacity

Answer 6

The amount of acid or base the buffer can neutralise before the pH begins to change an appreciable degree

Question 7

Acidosis

Answer 7

Refers to an excess of acid in the blood that causes the pH to fall below 7.35

Question 8

Alkalosis

Answer 8

Refers to an excess of base in the blood that causes the pH to rise above 7.45
