Why does a buffer solution will change in pH upon addition of acid or base?
Wiki User
∙ 14y ago
Buffering compounds are weakly ionised, addition of hydrogen or hydroxide ions (in modest amounts), shift the degree of ionisation of the buffer which produces an increase or decrease in the hydrogen or hydroxide ions provided by the buffer itself. This change in ionisation of the buffering compound approximately compensates for the addition.

A solution that is resistant to change in pH?
Solutions that resist change in pH when added to a strong acid or base are known as buffer solutions.
What is a solution that resists changes in the concentration of hydrogen ions caused by the addition of an acid or a base?
it is called a buffer. there would be minimal change in pH value if this solution is added
How does a buffer resist change in pH upon addition of a strong acid?
It accepts the hydrogen ions released by the acid.
which of the following best describes a solution that contains a buffer?
sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
When a base is added to a buffered solution, the buffer will?
When small amounts of acid or base are added to a buffer solution, the buffer functions to keep the pH from changing.
Does a weak acid resist a change in the pH?
It's easier to change the pH of a weak acid than a strong acid.

How you classify the solution as a best buffer solution?
A buffer solution is one involving a weak base/weak acid with its conjugate acid/base. In a buffer solution, the pH must be changed to only a small amount. Thus, any solution with a STRONG acid or a STRONG base is not a successful buffer solution because there would be a relatively large change in the initial pH.
What happens to the buffer solution pH 7 when acid is added?
When acid is added to a buffer solution at pH 7, the pH of the buffer solution will decrease. However, due to the presence of a conjugate base in the buffer solution, the buffer will resist the change in pH and try to maintain its original pH value. This is because the conjugate base will react with the acid and prevent a significant decrease in pH.
Describe a solution that contains a buffer?
Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.

How does the way a buffer stabilizes pH during addition of acid differ from the way the same buffer stabilizes pH during addition of base?
H+ and OH- ion responsible for acidic and basic behaviour are consumed by oppositely charged ions present in buffer solution to form a weak acid or base which is not much efficient to release H+ or oH- ion so pH does not change. But this happens only when strong acid or base is added to buffer in small amount.
When a base is added to a buffered solution, the buffer will?
When small amounts of acid or base are added to a buffer solution, the buffer functions to keep the pH from changing.
What can destroy buffer solution?
The buffer solution is destroyed if the amount of acid or base that can be absorbed is exceded.
Why would you add sulfuric acid to a mixture of oxalic acid and sodium oxalate?
This is an example of a buffer solution. if the sulfuric acid were added to a plain glass of water, it would have a massive change in pH. However, the buffer action of the oxalate-oxalic acid solution will decrease this change to something very minor (demonstrably to only hundredths or thousands, if the solution is made well, of the change it would have on pure water).
