What type of charge does a cationic coagulant have?

Negative
Neutral
Positive
Aqueous

The correct answer is: Positive

A cationic coagulant carries a positive charge. This characteristic is crucial in the context of water treatment processes. Cationic coagulants, such as aluminum sulfate or polyaluminum chloride, are used to help remove suspended solids and other impurities from water. When introduced into water, the positively charged particles of cationic coagulants attract negatively charged particles, such as dirt, clay, and organic matter. This interaction facilitates the formation of larger aggregates or flocs, which can then be more easily separated from the water during sedimentation or filtration processes. The role of charge in this coagulation process is significant, as it determines the effectiveness of the coagulant in binding with the contaminants present in the water. Understanding the charge properties of different coagulants is essential for optimal water treatment and ensuring safe drinking water.
