The pH scale measures the acidity or alkalinity of a solution on a logarithmic scale, where each whole number change represents a tenfold difference in hydrogen ion concentration. For example, a solution with a pH of 3 has ten times more hydrogen ions than a solution with a pH of 4, which corresponds to a concentration of (10^{-3}) moles per liter compared to (10^{-4}) moles per liter. Thus, pH values are inversely related to the concentration of hydrogen ions, expressed in powers of ten.

because they don't have enough acid in it.
the scale used to measure acid and bases is called a pH scale. the numbers range from 1-14 and go as following- to show an acid= 1-6 nuetral= 7 to show a base= 8-14
u can chek the hardness by pH scale...lolz

Neutrality is a pH=7,00.

On the pH scale, acids have a pH of less than 7.
All numbers below 7. Acidity increases with decreasing number, for example, 1 is the most acidic.
When a substance has a low pH, it means that it is acidic. pH is a measure of how acidic or basic a substance is on a scale of 0 to 14, with lower numbers indicating higher acidity. So, a substance with a low pH has a high acidity level.
The numbers 7.1 through 14 are the basic numbers.
The scale that measures how acidic or basic something is called the pH scale. It ranges from 0 to 14, with 7 being neutral, lower numbers indicating acidity, and higher numbers indicating alkalinity.
pH above 7 till 14 is basic. pH of 14 is most basic
pH scale
Example: 1, 2,3,.......7,8,9,.........14.
Anything above 7 is basic.
