The colors of anthocyanins are:
- red to pink: pH under 7
- purple: neutral
- green to yellow: basic, pH over 7
- colorless: very basic

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 2 numbers on the pH scale are the strongest bases?
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.
What is the pH of antarcids?
Antacids are used to neutralize acids, and are therefore bases, so their pH values must lie between 7 and 14 on the pH scale.
How is the pH scale used to measure strength of acids and bases?
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.
What is the pH scale of Barium hydroxide?
pH depends on concentration. However, the best way to compare bases (and acids) is to use the pKb value; the pKb of barium hydroxide is around -2, which makes it extremely basic.
What chemically does the pH scale measure?
all acids and bases. to the right at bases to the left are acids
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 the pH scale in terms of acids and bases?
it is a scale that measures liquid
What is pH scale how it is used?
a pH scale is something used for measuring the strengths of acids and bases.
How do scientists measure the strength of acids and bases?
they use the pH scale
How do you calculate the pH or ion concentrations for acids and bases?
By the use of pH scale.
Acids and bases near the ends of the pH scale are very?
Acidic or basic
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 2 numbers on the pH scale are the strongest bases?
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.
What is the scale called that measures the strength of acids and bases?
This scale is called the pH scale. Some say this stands for " the power if the hydrogen ", or " the power of hydronium. "
What is the differentiate between acids and bases?
An acid is below 7 on the pH scale and bases are above 7 on the pH scale. An acid can be a hydrogen donor, and a base is a hydrogen acceptor.
How are the strengths of acids and bases measured?
On a scale of 1-14 measuring the concentrations of Ph and POh.
