$<b>$What is pH?

The pH scale is alternatively sometimes called the pH-acid-base scale and sometimes just the acid-base scale.

Acidic solutions are those with pH less than 7, while basic solutions have pH greater than 7.

A solution is:

✔acidic when there are more H+ ions than OH- ions present
✔basic when there are more OH- ions than H+ ions present
✔neutral when there are equal number of H+ and OH- ions present.

pH is a measure of the hydrogen ion activity, typically in aqueous solution.

In pH, the p stands for -log10 and the H stands for hydrogen ion activity:

pH = -log10aH+

Acid and Base pH:-

Acid solutions have pH < 7. pH values lower than 0 are possible.

Basic solutions have pH > 7. pH values greater than 14 are possible.
