Using a UI indicator solution, or UI paper, pH 6.7 corresponds to a yellow/green colour
pH - around 4.8 color - dark brown
2B)
This is a pH indicator.
The color of Ph paper is supposed to change, depending on the Ph level of the liquid you placed it on. The color is dependent as well. When purchasing Ph paper, it comes with a guide on the box. It is best to use that.
Cabbage contain Anthocyanins called Cyanidin. These are responsible for changing color with pH. Changing the pH affects the shape of the molecule which, in turn, changes its wavelength absorption.
That depends on the pH.

A universal indicator changes color in response to the pH of a liquid. Do determine the pH of the liquid, you need to refer to a color chart that tells you which color indicates which pH.

The pH of bleach color is 13.
pH value of tap water is 6.Dark green color is observed.
This is a pH indicator.
the color of the chart represents the color that the pH test strip tuned there should be a decimal number the decimal number should be with the color so 7.0 is the normal pH level for a human

First of all it is NOT water at this pH level. It is an ALKALINE Solution. With a pH = 9.5 the colourt would be blue.
