Briefly discuss differences among the waters and note the difference in the chemistry of rainfall compared to the other waters.
Understand the Problem
The question is asking to analyze and compare the chemical composition of different lake waters alongside rainfall water. The user is likely looking to discuss variations in concentration and chemical makeup between the two types of water sources.
Answer
Rainwater is more acidic (pH ~5.7) due to dissolved gases, while seawater has a higher pH (8.2) due to salts.
Rainwater is more acidic with a pH around 5.7 due to dissolved gases like carbon dioxide, while seawater has a higher pH of 8.2. Rainwater typically contains fewer dissolved solids than other waters, such as seawater, which contains salts and other minerals.
Answer for screen readers
Rainwater is more acidic with a pH around 5.7 due to dissolved gases like carbon dioxide, while seawater has a higher pH of 8.2. Rainwater typically contains fewer dissolved solids than other waters, such as seawater, which contains salts and other minerals.
More Information
Rainwater tends to gather dissolved gases from the atmosphere, making it slightly acidic. Its low concentration of dissolved solids differentiates it from other natural waters like oceans, which have significantly higher salt and mineral contents.
Tips
A common misconception is that all natural waters have a neutral pH of 7. However, due to dissolved substances, this is usually not the case.
