0-6 and everything less than 7 (grade 7 science)
The pH of an acid solution is under 7.
Anything with a pH of 7 is neutral
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.
It's easier to change the pH of a weak acid than a strong acid.
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.
It contains an acid at 0.01M concentration.
The presence of an acid lowers the pH of the solution in water.
The presence of an acid reduces the pH.

The presence of an acid reduces the pH.
The pH value of an acid solution depends on its concentration and the temperature of the solution.
Neutral solution: pH =7Acidic solution: pH7.
The pH is under 7.
A solution with a pH of 2 is about 1000 times more acidic than a pH of 5. This does not necessarily mean an acid is stronger, though it may merely be in a higher concentration.
