Acids have pH values below 7.0. Bases have values above 7.0.
The strength of an acid or base is typically measured using the pH scale. Acids have a pH below 7, with lower pH values indicating stronger acids. Bases have a pH above 7, with higher pH values indicating stronger bases.
pH is a measure of the concentration of hydrogen ions in a solution, with lower pH values indicating higher acidity and higher pH values indicating higher alkalinity. Acids have pH values below 7, while bases have pH values above 7. Acids release hydrogen ions in water, lowering pH, while bases release hydroxide ions, raising pH.
Acids and bases are described in the pH scale based on their strength. For instance,lactic acid has pH 6,but curd,obtained from milk itself has pH 3! HCl is called as the "king of acids" with pH 1. {on the pH scale,if any substance has pH 7, its considered acidic, while anything above 7 is basic.} Acids or Bases can be considered as acidic or basic by the colour changes in the pH scale{eg:red to orange[neutral]to violet}.
The pH scale is a measure of the acidity or basicity of a solution. It ranges from 0 to 14, with 7 being neutral. Acids have pH values below 7, bases have pH values above 7.
From 0 ( or below ) to 7 is an acid, from 7 to 14 ( or above ) is a base and neutral is at 7, more or less.
Alkalis (bases) react with acids to neutralize them, so in one sense, they can be considered as "opposite" of acids. Bases produce pH values >7 and acids produce pH values <7.

Bases have values higher than 7 Substances with a pH of 7 are neutral Acids have a pH below 7
The pH scale is a measure of the acidity or basicity of a solution. It ranges from 0 to 14, with 7 being neutral. Acids have pH values below 7, bases have pH values above 7.
From 0 ( or below ) to 7 is an acid, from 7 to 14 ( or above ) is a base and neutral is at 7, more or less.
Acids typically have a pH range of 0-6.9, with lower values indicating stronger acidity. Bases usually have a pH range of 7.1-14, with higher values indicating stronger basicity. A pH of 7 is considered neutral.
buffers, they help bases and acids to become weak bases and acids. (making the pH not so extreme)
Acids have a lower PH and bases have a higher PH.
Chemists use the pH scale to describe the relative strength of an acid or base. Acids have a pH below 7, with lower values indicating stronger acids. Bases have a pH above 7, with higher values indicating stronger bases.
