Calcium Hypochlorite – Properties, Applications & Safety

Introduction

Calcium Hypochlorite (Ca(ClO)₂) is a white or grayish solid widely used as a disinfectant, bleaching agent, and sanitizer. It is commonly known as chlorinated lime or simply pool chlorine due to its popularity in swimming pool and drinking water treatment.

With a strong oxidizing action, calcium hypochlorite is one of the most effective and economical chlorine-based chemicals for controlling bacteria, algae, and pathogens.
