can you be more specific? "the" acid?
pH of buffered solutions generally will not change upon dilution, following the henderson-hasselbach.
however, pH of strong acids will change, following the standard equation:
pH = -log[H+]

What is the effect of dilution on the pH of strong acid?
the pH decreases since dilution affects the cocentration of H+ found ... thus the pH so the more the water is , the less the concentration of H+ is for the same amount of H+
Is it true that a ten-fold dilution of a strong acidic solution will decrease the pH by 1?
No, it is false. A ten-fold dilution of an acid will INCREASE the pH by 1 unit. Remember pH is 0-14 where 0 is most acidic. Diluting ten-fold on a logarithmic scale will increase the pH.Conversely, a ten-fold dilution of an alkali/base will increase the pH by 1 unit.
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
Will the pH change when an alkali is added to an acid?
Yes. The pH will increase.
How does pH change when an acid is added to a base?
The pH lowers from around 14 to a lower number as acid is added.

What is the maximum pH attained upon infinite dilution of an acid?
Trick question ? If you dilute with water then eventually the pH will approach 7 (approximately, since water seldom has a true pH of 7).
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
How does neutralization change the pH value of an acid?
When an acid is neutralized, its pH value is changed to be around 7 and it is no longer an acid.
Will the pH change when an alkali is added to an acid?
Yes. The pH will increase.
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 does pH change when an acid is added to a base?
The pH lowers from around 14 to a lower number as acid is added.
What happens to the pH of hydrochloric acid when it is diluted?
The pH of basic solutions will drop (become less basic) as the solution is diluted. However, if the solution contains a buffer, the pH will remain nearly constant upon dilution.
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
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 neutralization change the pH value of an alkali?
when an acid is neautrilized, its ph value is changed to be around 7 and it is no longer a acid
