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.

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.
What would happen to the overall pH if you dumped a strong acid into a solution that was slightly alkaline?
The final pH of the mixture will depend on how much of the strong acid you add. The initial amount of acid will neutralize the alkaline solution, and if there is enough of the strong acid, the final pH will then become acidic, i.e. pH < 7.
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.
A 0.12M solution of an acid that ionizes only slightly in solution would be termed?
It would be named as a dilute solution of a weak acid.
Is strontium chloride an acid or base?
Neither, it is a neutral salt (conjugated with the strong acid HCl)
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.

What is the pH value of sugar?
Which sugar? How strong a solution? In the main, just slightly acid, I would imagine.

Is a water solution of a strong acid always concentrated?
a water solution of a strong acid is what?
What would happen if you dumped a strong acid into a slightly alkaline solution?
A neutralization reaction occur with the formation of a salt.
An acid that ionizes almost completely in solution is called a acid?
Strong
Standardising HCl using Na2CO3 titration. textbook says the solution at the equivalence point is slightly acidic. is it and why?
it depends on the strength of the acid and base used: so, strong acid + strong base = neutral equivalence point strong acid + weak base = acidic equivalence point weak acid + strong base = basic equivalence point In this case, HCl is a strong acid, and Na2CO3 a weak base. Therefore, the equivalence point will be slightly acidic.
What is the opposite of a strong acid?
It depends which part of the stong acid concept you are concerned with: A weak acid is the opposite of a "strong" acid A strong base is the opposite of a strong "acid" A neutral solution is the oppposte of a strong acid (a reactive solution)
