3.7 Water Lab Review - Ocean Acidification Flashcard

Front

What is the normal pH of ocean water?

Back

Slightly above 8.

Front

What is the approximate pH of a solution that appears similar to a pH of 7.9?

Back

7.9.

Front

What gas is increasing in the atmosphere and causing ocean acidification?

Back

CO2 (Carbon Dioxide).

Front

What happens to the color and pH of a solution when photosynthetic algae absorb CO2 during photosynthesis?

Back

The color returns to its original state and the pH increases.

Front

What pH range indicates a basic solution?

Back

pH~8.5-9.

Front

What color indicates an acidic solution in a pH indicator guide?

Back

Typically yellow or red.

Front

What is the effect of increased CO2 levels on ocean water?

Back

It leads to ocean acidification.

Front

What role do photosynthetic algae play in the pH of ocean water?

Back

They absorb CO2, which can increase the pH.

Front

What is the significance of a pH of 7 in terms of acidity?

Back

It is neutral; neither acidic nor basic.

Front

How does cellular respiration affect the pH of a solution with algae?

Back

It can lower the pH by releasing CO2.
