The pH scale was developed by the Danish chemist Søren Sørensen in 1909. It is a measure of the acidity or alkalinity of a solution, ranging from 0 to 14. A pH below 7 indicates acidity, a pH of 7 is neutral, and a pH above 7 indicates alkalinity. It is used to quantify the concentration of hydrogen ions in a solution to classify substances as acids, bases, or neutral.

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.
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.
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 does PH scale describes?
The PH scale is the measurement of acids and bases. 8 and up are bases. 6 and lower are acids. 7 is neutral.
What is pH scale how it is used?
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.
How do scientists measure the strength of acids and bases?
they use the pH scale

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.
What scale do chemists use to describe th relative strngth of an acid or base?
Chemists use the pH scale to describe the relative strength of an acid or base. Acids have pH values less than 7, while bases have pH values greater than 7. The lower the pH value, the stronger the acid, and the higher the pH value, the stronger the base.
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 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
