Unit 6 Ocean Acidification Checkpoint

Front

What is ocean acidification?

Back

Ocean acidification refers to the decrease in pH levels of ocean water due to the absorption of carbon dioxide (CO2) from the atmosphere.

Front

What is the chemical formula for carbonate ion?

Back

CO₃²⁻

Front

What does a low pH indicate about a solution?

Back

A low pH indicates that the solution is acidic.

Front

How does increased CO2 in the atmosphere affect ocean water?

Back

Increased CO2 leads to lower pH levels in ocean water, making it more acidic.

Front

What is the pH range for acidic solutions?

Back

The pH range for acidic solutions is from 0 to 6.

Front

What is the pH of pure water?

Back

The pH of pure water is 7, which is considered neutral.

Front

What are the main components that marine organisms use to build their shells?

Back

Marine organisms primarily use calcium and carbonate ions to build their shells.

Front

What happens to marine life as ocean acidity increases?

Back

Increased ocean acidity can harm marine life, particularly organisms with calcium carbonate shells, making it harder for them to survive.

Front

What is the significance of a pH of 8.1 in ocean water?

Back

A pH of 8.1 indicates that the ocean water is slightly basic.

Front

What is the role of carbonate ions in marine ecosystems?

Back

Carbonate ions are essential for the formation of shells and skeletons in many marine organisms.
