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\?

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\?

Answer

Brief Explanations:

The pH - scale ranges from 0 - 14. Solutions with pH < 7 are acidic, pH = 7 is neutral, and pH > 7 is basic. Red - cabbage broth acts as an indicator. Red or pink solutions (pH 2 - 4) are acidic. A purple - to - blue solution (pH 7) is neutral. A yellow - green solution (pH 11) is basic.

Answer:

  1. Acidic
  2. Neutral
  3. Basic
