The colors of anthocyanins are:
- red to pink: pH under 7
- purple: neutral
- green to yellow: basic, pH over 7
- colorless: very basic
The PH scale is the measurement of acids and bases. 8 and up are bases. 6 and lower are acids. 7 is neutral.
The pH scale goes from 1-14. The strongest bases will be at 12 and 13 and the strongest acids will be at 1-2.
Antacids are used to neutralize acids, and are therefore bases, so their pH values must lie between 7 and 14 on the pH scale.
Acids have a pH under 7, alkalis have a pH bigger than 7.
They use a pH meter. The scale is called pH scale, any value below 7 is acidic (the lower, the more acidic) Any value more than 7 is basic(the higher, the more basic) 7 is neutral, like water for example.
The PH scale is the measurement of acids and bases. 8 and up are bases. 6 and lower are acids. 7 is neutral.
a pH scale is something used for measuring the strengths of acids and bases.
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.
they use the pH scale
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.
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.
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.
If I remember right bases are a neutral flavor while acids are sour by using 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}.
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.
Bases have values higher than 7 Substances with a pH of 7 are neutral Acids have a pH below 7
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.
