Question

The pH scale measures how acidic or basic a substance is. Lemon juice is said to have a pH of less than four and greater than 1.5. Model the normal range of pH values of lemon juice, using a compound inequality

Answer 1

The compound inequality that gives the normal range for the pH values of lemon juice is given by:

$1.5 < pH < 4$

What is a compound inequality?

A compound inequality is modeled by:

$a < x < b$

Which means that x is greater than a and less than b. In this problem, the pH is greater than 1.5 and less than 4, hence the inequality is given by:

$1.5 < pH < 4$
