a pH scale is something used for measuring the strengths of acids and bases.


Why acids and alkalines are equal?

Acids and bases are not equal; they are opposites on the pH scale. Acids have a pH below 7, while alkalines (bases) have a pH above 7. Acids donate hydrogen ions, while bases accept them.

What is the pH scale in terms of acids and bases?

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.


How are the strengths of acids and bases measured?

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.


What is the scale called that measures the strength of acids and bases?

The scale that measures the strength of acids and bases is called the pH scale. It ranges from 0 to 14, with values below 7 indicating acidity, values above 7 indicating alkalinity, and a pH of 7 being neutral.


Bases create a sour taste in your mouth?

If I remember right bases are a neutral flavor while acids are sour by using the PH Scale.


How are acids and bases described in the pH scale?

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}.


What scale do chemists use to describe the relative strength of an acid or Bose?

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.


What is true about bases on the pH scale?

Bases have values higher than 7 Substances with a pH of 7 are neutral Acids have a pH below 7


What has more OH- ions acids or bases?

Bases have more OH- ions than acids. Acids typically contain more H+ ions, while bases contain more OH- ions. The pH scale represents the concentration of H+ ions, with acids having a pH lower than 7 and bases having a pH higher than 7.
