How do buffers work?
They resist large and /or abrupt changes in pH. Made from a weak acid and it's conjugate base.

If you want to change the pH of a solution slightly do you use a strong or weak acid?
It depends on how you want to change the pH and by how much, and for what reason.Acids will lower the pH, while bases raise it.Using a strong acid will make a large change in pH; a weak acid will result in a small change for the same amount of acid, and the effects of a weak acid can be (somewhat) finetuned.Some acids contain ions that can affect the other components in solution; using a particular acid type might be necessary for that reason alone.
What are compounds that resist changes in pH?
A buffer resists pH change.
Does weak acid always act to change the pH when placed in water?
Not necessarily, if a solution of a strong acid is very dilute it will have a higher pH than some weak acids in higher concentrations.

Will H2C2O4 increase decrease or no change in the pH when added to water?
the pH will decrease slightly as oxalic acid is a weak acid.
How does a buffer resist change in pH upon addition of a strong acid?
It accepts the hydrogen ions released by the acid.

If you choose to change the pH of a solution very slightly should you add a strong acid or weak acid?
You would likely add a weak acid. Trying to produce a small change in pH with a strong acid would require a very small amount of acid, which would be difficult to measure properly.
How do you know if an acid is weak?
An acid is weak if it has a PH of seven or higher.
What pH does a weak acid have?
Weak acids have a pH around 4-7
What are compounds that resist changes in pH?
A buffer resists pH change.
What is pH of a strong acid and pH of a weak acid?
A strong acid id PH 1 or 2 and a weak acid is a number between 5 or 6 Not 7 because that is neutral
Is a chemical with a pH level of 4 a weak acid?
Not very weak, it is a moderately weak acid.
