ENEV 321: L-11 Acid Rain and Its Impacts

These flashcards cover key vocabulary and definitions related to acid rain and its impacts, focusing on the chemical processes and methods of analysis discussed in the lecture.

Acid Rain

Rain that has become acidified due to the presence of sulfuric acid, nitric acid, and carbonic acid.

Sulfate Reduction

The process by which sulfate is converted to hydrogen sulfide (H2S) under anaerobic conditions.

Hydrogen Sulfide (H2S)

A chemical compound that contributes to the unpleasant odor associated with acid rain.

Crown Corrosion

A form of corrosion that occurs in sewer pipes due to the presence of acidic compounds.

Odor Problem

An issue caused by the reduction of sulfate to hydrogen sulfide in environments lacking oxygen.

Gravimetric Analysis

A method of analysis used to determine the mass of an analyte.

Turbidimetric Analysis

A method used to measure the turbidity or cloudiness of a solution.

Automated Methylthymol Blue

A method for analyzing wastewater that uses dye to indicate pH.

Sewer Pipe Corrosion

Corrosion in sewers often caused by chemical reactions involving acid rain components.

Prevention of Crown Corrosion

Methods typically focus on controlling pH and reducing sulfate presence.
