Acids and Their Effects on Marine Life

Front

What is ocean acidification?

Back

Ocean acidification refers to the process by which the ocean becomes more acidic due to increased levels of carbon dioxide (CO2) in the atmosphere, leading to a decrease in pH levels.

Front

What is the pH scale?

Back

The pH scale measures how acidic or basic a solution is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What is the impact of increased CO2 on marine life?

Back

Increased CO2 leads to ocean acidification, which can harm marine organisms, especially those with calcium carbonate shells or skeletons, like corals and shellfish.

Front

What is the chemical formula for carbonic acid?

Back

H2CO3

Front

How does carbon dioxide enter the ocean?

Back

Carbon dioxide enters the ocean through the atmosphere, where it dissolves in seawater.

Front

What is the role of photosynthesis in ocean ecosystems?

Back

Photosynthesis by marine plants and phytoplankton produces oxygen and absorbs CO2, helping to regulate the ocean's pH.

Front

What are some effects of ocean acidification on coral reefs?

Back

Ocean acidification can weaken coral structures, hinder growth, and reduce biodiversity in coral reef ecosystems.

Front

What is the relationship between pH and acidity?

Back

As pH decreases, acidity increases; a lower pH indicates a more acidic solution.

Front

What is a buffer in the context of ocean chemistry?

Back

A buffer is a substance that helps maintain a stable pH in the ocean by neutralizing acids or bases.

Front

What is the significance of calcium carbonate for marine organisms?

Back

Calcium carbonate is essential for marine organisms like corals and shellfish to build their shells and skeletons.
