Answer

Explanation:

Step1: Recall pH - scale properties

Lower pH values indicate higher acidity and higher pH values indicate higher alkalinity.

Step2: Match colors to pH values

By comparing the colors on the test - papers with the color - coded pH scale provided:

  • Paper A has a color corresponding to a pH of about 10.
  • Paper B has a color corresponding to a pH of about 6.
  • Paper C has a color corresponding to a pH of about 8.
  • Paper D has a color corresponding to a pH of about 2.

Step3: Order from most acidic to most alkaline

The order from most acidic (lowest pH) to most alkaline (highest pH) is: Paper D (pH = 2), paper B (pH = 6), paper C (pH = 8), paper A (pH = 10).

Answer:

Paper D, paper B, paper C, paper A
