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

$1.5 < pH < 4$

<h3>What is a compound inequality?</h3>

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:

$1.5 < pH < 4$
