A pH scale determines whether a solution is acidic or alkaline. 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 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) $4.1 \leq h < 4.3$, acidic
C) $4.1 \leq h \leq 4.3$, acidic
D) $4.1 < h \leq 4.3$, alkaline

Quizplus · Accepted Answer

The pH range of 4.1 through 4.3, inclusive, is correctly represented as $4.1 \leq h \leq 4.3$, and because it is less than 7, it is acidic.
