Cleaning & SanitizingQuestion 134 of 319
Chlorine sanitizer is MOST effective when the solution's pH is:
a.Slightly acidic to neutral (about 6.5–7.5)
b.Strongly alkaline (above 10)
c.Strongly acidic (below 3)
d.pH does not affect chlorine
Explanation
Chlorine bleach works best between pH 6.5 and 7.5. As pH rises above 8, more of the chlorine converts to a less effective form (hypochlorite ion). Very low pH boosts activity but is corrosive and unsafe. Tap water and chlorine concentration are the practical variables food workers control.
