Is Distilled water corrosive

Answer 1

Typically no. It does depend on the processing of the water however. If there is post filtering that removes the minerals and leaves it essentially pure H2O, then you have a relatively aggressive solvent. Distillation alone is not capable of producing water pure enough to have this property.

Answer 2

Distilled water is not inherently corrosive because it does not contain any dissolved minerals or impurities. It is often used in applications where corrosion must be minimized, such as in laboratory experiments or as a coolant in car engines. However, distilled water can become corrosive if it comes into contact with metals that can create an electrolyte solution due to its lack of buffering capacity.
