What is the change in PH when an alkali is slowly added to an acidic solution?
The actual answer depends on the strength of the acid / alkali used. However the pH will change from around 1-6 to 8-14 depending on the strength of the acid / base. pH ~1 for strong acid pH ~6 for weak acid pH ~8 for strong base pH ~14 for strong base
What is a substance that resists a pH change when small amounts of acid or base are added?
buffer
What is added to an acid to maintain its pH?
a base
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.

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.

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.
Will the pH change when an alkali is added to an acid?
Yes. The pH will increase.
Why does a solution of a conjugate acid base pair behave as a buffered solution?
The resist pH change in the following way: If you add a strong acid to the buffer solution, the conjugate base gets protonated, but the pH is not significantly changed. If you add a strong base to the buffer, the conjugate acid gets deprotonated, and again the pH is not changed very much. If you only had one component (let's say just the conjugate base), then it would not be able to resist change in pH if you added a strong base to the solution (although it would still counteract the affect of added acid).
What is a base on the pH scale?
A base is anywhere from 8 to 14 on the Ph scale. If a base of about 8 is added to and acid of about 6, the Ph will be balanced out.
Why do you need indicators of chemical change?
To indicate the change of its Ph nature either from acid to a base or a base to an acid
Does water change the pH level of vinegar?
no. water just dilutes the acid but the PH will not change unless an acid or alkali is added
