These test tubes contain solutions of various colors, since they have been mixed with broth from red cabbage. The approximate pH values are noted.

How would you best describe the red or pink solutions labeled "2-4"?

How would you best describe the purple to blue solution labeled "7"?

How would you best describe the yellow-green solution labeled "11"?

acidic

neutral

basic

The answer and the explanation given below:

Explanation:

The pH is a scale which is used to identify a solution whether it is acidic, basic or neutral. The pH scale ranges from 0 to 14. A pH 7.0 is neutral which is of pure water. The range from 0.0 to 6.9 is acidic due to presence of a high concentration of hydrogen ions (H⁺) in the solution as compared to pure water. The range 7.1 to 14.0 is basic due to presence of a low concentration of hydrogen ions (H⁺) in the solution as compared to pure water.

The red or pink solutions labeled "2-4" will be acidic as per pH scale. The purple to blue solution labeled "7" will be neutral as per pH scale. The yellow-green solution labeled "11" will be basic or alkaline as per pH scale.
