Acidity in lakes can increase due to factors such as acid rain from industrial pollution and vehicle emissions, runoff from agricultural activities that introduce excess nutrients, and natural sources like decomposition of organic matter. These inputs can lower the pH of the water, making it more acidic and harmful to aquatic life.

What does an increase of 1 pH number represent?
10x increase in acidity
Can you make lakes less acidic?
Yes, lakes can be made less acidic through a process called liming, where alkaline materials such as limestone are added to neutralize the acidity. This can help buffer the pH levels and improve the overall health of the lake ecosystem. However, it is important to consider the underlying causes of acidity, such as pollution or acid rain, in order to address the root of the issue effectively.
When limestone is added to lakes why is it powdered?
Limestone is powdered when added to lakes to increase its surface area, allowing for quicker dissolution and reaction with acidic water. This helps to neutralize the acidity and restore the pH balance in the lake, promoting healthier aquatic ecosystems.
What happens to the size of an egg in vinegar?
When an egg is placed in vinegar, the shell dissolves due to the vinegar's acidity. This causes the egg to increase in size as the vinegar penetrates the egg's membrane, causing it to swell.
How does neutralization reactions help reduce the acidity of lakes caused by acid rain?
Neutralization reactions involve mixing an acid with a base to produce a salt and water, resulting in a decrease in acidity. In the context of lakes affected by acid rain, adding a base, such as limestone (calcium carbonate), helps neutralize the acid and raise the pH level, reducing the acidity of the water. This process can help restore the balance in the lake's ecosystem and improve conditions for aquatic life.
Why are lakes treated with limestone powder?
To reduce their acidity.
What causes the acidity of water entering lakes and watercourses?
i can't believe this question hasn't been answered i can't believe this question hasn't been answered
How can acidity be treated?
You can treat answer rain in lakes by adding limestone into the lake
What does an increase of 1 pH number represent?
10x increase in acidity
Can pH value be related to acidity?
Yes to lower acidity you can add alkalines which increase Ph values

Pollution due to coal burning most frequently tend to affect lakes by?
increasing acidity
What type of energy causes the evaporation of water from lakes oceans and rivers?
The kinetic energy of the molecules is the source; the evaporation increase of course at high temperatures.
What is acidulate?
An acidulant is a food additive used to increase acidity.
What is an acidulant?
An acidulant is a food additive used to increase acidity.
How does water in ponds and lakes become acidic?
Ponds and lakes become acidic via acid rain when the CO2 rises into the atmosphere and is absorbed and then when it falls back onto the earths surface it can runoff into ponds and lakes usually being accompanied by things such as weed killers and human waste therefore its acidity becomes more concentrated therefore when it finally enters the lakes or ponds in large quantities it causes the lakes and ponds acidic levels to change.
When limestone is added to lakes why is it powdered?
