Is rain safe

In most locations rain is safe. Things that would make unsafe is what you are using it for, the pH of the rain, the purity of rain, and the amount of rain. The pH, or acidity of the rain affects the quality of the rain greatly. Unpolluted rain is slightly acid with a pH of 5.2 but when water and carbon dioxide come together it makes a chemical reaction containing H3O or acid rain. Acid rain is typically not safe for drinking and can cause polltution of lakes and destruction of plants. The purity of rain is another factor. Rain that runs through the rivers may be safer to drink than rain that fell into a marsh because of all the dirt which may contain lots of bacteria and other dangerous substances. Also, rain is unsafe depending on the amount of rain. Too much rain can lead to floods which can cause death, destruction of structures, and crop devastation, also too little rain leads to drought which leads to death by dehydration and crop death. Use common sense when using rain. Rain that's okay to walk in may not be safe to bath in. Rain that's okay to bath in may not be safe to drink.
