The correct option is this: SAMPLE A IS ACIDIC AND SAMPLE B IS ACIDIC.

pH is a measure of the quantity of hydrogen ions that are present in a sample. Typically, pH values range from 0 to 14. A sample is said to be acidic if its pH fall between 1 and 6. pH value of 1 is the most acidic while pH value is the least acidic. Thus, the two samples given in the question are acidic, but sample A is more acidic than sample B.

Given the data from the question, Andy can conclude that:

  • Sample A is acidic
  • Sample B is acidic

What is pH ?

This is simply a measure of the acidity / alkalinity of a solution.

The pH measures the hydrogen ion concentration while the pOH measures the hydroxide ion concentration

pH scale

The pH scale is a scale that gives an understanding of the variation of the acidity / alkalinity of a solution.

The scale ranges from 0 to 14 indicating:

  • 0 to 6 indicates acid
  • 7 indicates neutral
  • 8 to 14 indicate basic

With the above, information in mind, we can conclude as follow:

  • Sample A (pH of 4) is acidic
  • Sample B (pH of 6) is acidic
