Why are lakes limed?
Lakes are limed because of acid rain, without the added alkali in the water the pH balance of the lake would be pushed further towards acidic and this would be very detrimental to the aquatic life which have quite narrow tolerance bands for pH. So to keep the pH at roughly the same level lime is added.
Can a lake near a volcano become acidic?
Yes, a lake near a volcano can become acidic due to volcanic activity. When a volcano erupts, it can release gases such as sulfur dioxide, which can dissolve in water and form sulfuric acid, lowering the pH of the lake. Additionally, the leaching of minerals from volcanic rocks can also contribute to increased acidity. These changes can significantly impact the ecosystem of the lake.
Why do you think limestone is sprayed into a lake that is affected by acid rain?
Limestone is sprayed into lakes affected by acid rain to neutralize acidity and restore the water's pH balance. The calcium carbonate in limestone reacts with the hydrogen ions in the acid, helping to mitigate harmful effects on aquatic life and improve water quality. This process can enhance the overall ecosystem health, supporting fish populations and other organisms that may be endangered by low pH levels. Additionally, it promotes the recovery of sensitive habitats that have been degraded by acidification.
What can be done to restore the pH of the lake to a value of seven?
To restore the pH of a lake to seven, reducing acidic inputs such as pollution from industrial sources or runoff from agricultural activities is essential. Implementing measures like liming, which involves adding alkaline substances to neutralize acidity, can help raise the pH level of the lake. It's also crucial to promote practices that reduce nutrient loading and enhance overall water quality to support a balanced aquatic ecosystem.
Why is powdered limestone sometimes deliberately added to lakes in countries like Norway and Sweden?
Powdered limestone is added to lakes in Norway and Sweden as a restoration technique to combat acidification caused by acid rain. Limestone acts as a buffer, neutralizing the acidity in the water and improving the pH levels to support aquatic life. This helps to restore the ecological balance of the lake and promote biodiversity.
How can you reduce the amount of acidity in a lake?
You could add some alkali compounds into it to neutralize some amounts of the acidity in a lake. For the long term, you could find the source of the acidity and control the emission of it. For example, sulfur dioxide released into the air can dissolve in water and fall as sulfuric acid, acidifying the lake.
Where is a crater full of acidmaking an acid lake?
A well-known crater filled with acid, creating an acid lake, is the Kawah Ijen crater in Indonesia. The lake is known for its striking turquoise color and high acidity due to sulfuric acid from volcanic gases reacting with water. This unique environment is a result of ongoing volcanic activity, making it a fascinating yet hazardous site.
Why is lime added to acidic lakes?
Lime is a strong base. When you add a base to an acid it turns it neutral. So by adding the lime to the water after a while it'll turn into precipitation itself and neutralize the acid. This is also known as acid-base neutralization.
Suppose a lake were polluted by acid rain how might you make it safe again for animals and plants to live there?
If a lake were polluted by acid rain, it would have to be detoxified before it would be safe again for plants and animals. The detoxification process would involve introducing into the lake a substance that could neutralize the bad chemicals.
What neutralizes lake water with low pH a base or an acid or a salt?
If water is low in pH then base or basic salts can be added to neutralize the excess of acid. It will bring pH up, but it is advised to be very careful. Natural waters have pH value between 4.5 and 6.5 depending on many ecological circumstances. Even swimming pools and garden ponds are spoiled by unclassified 'home' chemists!

How might one correct the pH of a lake with the reading of 3?
Because that lake has a acidic pH, you can neutralize it by putting basic pH in it.

If a chemical spills in the humber river lake or a stream in your region where would it go?
It would go in Lake Ontario and i think into smaller steams...
How do you lower a lakes pH?
To lower a lake's pH, you can introduce acidic substances such as alum or sulfuric acid. These substances will react with the alkaline compounds in the water, neutralizing them and lowering the pH level. It's important to carefully monitor the pH levels and consult with a water quality expert before attempting to adjust the pH of a lake.
