The term “acid rain” was first coined by Robert Angus Smith in 1852, in a report titled “On Air and Rain: The Beginnings of Chemical Climatology”. Smith, a Scottish chemist, had been studying the effects of industrial pollution on the environment and noted the presence of sulfuric and nitric acids in rainwater. His work laid the foundation for understanding the causes and consequences of acid rain, which has become an important environmental issue in recent years.
When Was the Term “Acid Rain” First Used?
Angered by the damage that industrial emissions were doing to Scandinavian lakes and forests, Swedish scientist Svante Arrhenius coined the term “acid rain” in the late 1800s. However, it wasn’t until the 1950s that the term gained widespread recognition.
Here’s a timeline of key events:
1852
- Robert Angus Smith publishes a paper on the effects of industrial pollution on rainfall in Manchester, England.
1896
- Swedish chemist Svante Arrhenius publishes a paper entitled “On the Influence of Carbonic Acid in the Atmosphere on the Temperature of the Ground,” which discusses the potential for industrial emissions to acidify rainwater.
1952
- Norwegian scientist Eigil Baalsrud publishes a paper on the acidity of precipitation in Norway, and uses the term “acid rain” to describe it.
1955
- A group of Swedish scientists publish a report on the effects of acid rain on Scandinavian lakes and forests, and the term “acid rain” becomes more widely used.
1963
- The first international conference on acid rain is held in Stockholm, Sweden.
1970s
- Acid rain becomes a major environmental issue in Europe and North America.
1980s
- The United States and Canada sign the Acid Rain Control Agreement, which aims to reduce sulfur dioxide emissions.
1990s
- Emissions of sulfur dioxide and nitrogen oxides decline in Europe and North America, and acid rain levels decrease.
2000s
- Acid rain remains a problem in some parts of the world, particularly in developing countries.

Question 1:
When was the term “acid rain” first used?
Answer:
The term “acid rain” was first coined by Robert Angus Smith in 1852.
Question 2:
What is the pH range of acid rain?
Answer:
Acid rain typically has a pH value below 5.6, which is the pH of normal rain.
Question 3:
What are the main causes of acid rain?
Answer:
Acid rain is primarily caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere, which react with water vapor to form sulfuric acid and nitric acid.
Well, there you have it, folks! The term “acid rain” has been around for over a century, and it’s still a very relevant issue today. I mean, who wants to go outside and have their hair melt, right? Thanks for hanging out and geeking out on science with me. If you liked this little jaunt through the annals of acidity, be sure to drop by again for more word nerdiness and historical tidbits.
