There are several things that cause changes in levels of pH in lakes. 1 Photosynthesis affects levels of pH In the morning, pH levels are low with higher amounts of CO2 content in the water, which form carbonic acid. As the sun comes up, increasing the occurance of photosynthesis, O2 levels increase and the pH goes up during the day. 2 Pollutants Carbondioxide is the chief pollutant. It doesn't seem like this necessary element should be such a huge problem, but it is. The problem is that there are not enough plants to use up all of the excess CO2. The excess CO2 results in acid water. The excess CO2 comes from the CO released from our cars, manufacturing plants and a plethora of other places. It is released into the atmosphere. It comes down as rain. It washes it down into our lakes. Contaminates the fish, the water we drink, ect. It' not just carbon dioxide either. It's also fertilizers! Farming, gardening. The question you have asked would take a mouth full to answer! I just took a class last fall on this very topic and there is still much more to say about it!

CoachAn increase in pH levels in lakes can be caused by factors such as acid rain neutralization, algal blooms leading to photosynthesis, and the introduction of agricultural runoff containing basic compounds like lime or calcium carbonate. These processes contribute to higher pH levels by reducing the acidity of the water body.

What causes a high PH level?
A high pH level is typically caused by substances that are basic or alkaline in nature. Common sources include certain cleaning products, soaps, and chemical additives in water. Overuse of alkaline substances or a decrease in acidic compounds can lead to an increase in pH levels.
What causes low pH levels in a solution?
Low pH levels in a solution are caused by an increase in the concentration of hydrogen ions (H) in the solution. This increase in hydrogen ions makes the solution more acidic, resulting in a lower pH level.
Does the increase or decrease of CO2 affect the pH level?
Yes, the increase of CO2 can decrease the pH level of a solution, leading to acidification.
How does the age of an egg affect its pH level?
As an egg ages, carbon dioxide naturally escapes through the pores in the eggshell, which causes the pH level to increase. In other words, older eggs will have a higher pH level than fresher eggs. This change in pH can affect the texture and cooking properties of the egg.
What causes acidity in lakes to increase?
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.
