True or False: Rainwater is the purest form of water.

Answer:

False

Explanation:

According to the USGS, “Rainwater is usually fresh and clean, but it still contains small amounts of particulates that have been blown into the air by winds. Rainwater contains tiny particles of dust and dissolved gases, such as carbon dioxide and sulfur dioxide (acid rain). That doesn’t mean rainwater isn’t very clean—normally only about 1/100,000th of the weight of rain comes from these substances. For really pure water, you might want to look at distilled and deionized water. Distilled water comes from water vapor condensing after it has evaporated. Rain is produced by water evaporating from the earth, oceans, other water bodies and icecaps condensing in the sky, and even from you when you exhale. So, in a way, the distillation process is responsible for rainwater.” (Source: USGS)
