Question

The pH scale measures a solution's acidity or alkalinity. The pH scale runs from 0 to 14, with 0 being the most acidic and 14 being the most alkaline. A pH of 7 is neutral (distilled water has a pH of 7). Write the pH range for the following as an inequality and label the substance as acidic or alkaline.

Jerry's Fizzy Cola: 4.1 through 4.3, inclusive

A. 4.1 ≤ h ≥ 4.3, alkaline
B. 4.1 < h < 4.3, alkaline
C. 4.1 ≤ h ≤ 4.3, acidic
D. 4.1 ≤ h < 4.3, acidic

Answer 1

If we are to write the pH range for the Jerry's Fizzy Cola as an inequality and label the substance as acidic or alkaline, given the data 4.1 through 4.3 (inclusive), this would be the result:

C. 4.1 ≤ h ≤ 4.3, acidic
