Massachusetts Wastewater Practice Exam

Water is considered a non-corrosive substance primarily due to its neutral pH of around 7, which indicates that it is neither acidic nor basic. This property means that water does not have the ability to react adversely with substances, causing damage or degradation. In comparison, substances like acids, ammonia, and bleach are known for their reactive qualities. Acids can corrode metals and other materials, ammonia can react violently with certain chemicals, and bleach is a strong oxidizer that can degrade various organic materials. Therefore, water stands out as a stable and non-reactive solvent in many contexts within wastewater management and other applications. Its non-corrosive nature makes it essential in both natural and engineered systems.
