Neutral: when a solution contains no excess
of either [H+] or hydroxide ions.
Basic: when a solution contains an excess
of hydroxide ions
Acidic: when a solution contains an excess
of H+ ions

[H+] = [OH-] Neutral solution
[H+] > [OH-] Acidic solution
[H+] < [OH-] Basic solution
-------------------------
Acidic solutions have pH values that are less than 7.0
Basic solutions have pH values greater than 7.0

جدا مهم تعرفي شو يعني buffer
A solution’s ability to resist pH changes when a base or acid is added to it is called its buffer capacity.
