Which mineral would you add to a lake to neutralize acidic conditions (increase the pH)?

• Acetic acid

• Calcium carbonate

• Ammonia

• Bleach

Which of the following statements is true about both photochemical smog & acid rain?

• Nitrogen oxides are important primary pollutants.

• Sulfuric acid is a secondary pollutant involved in both.

• Tropospheric ozone is produced in both.

• A solution to both is reducing the number of gas-powered vehicles on the road.

What is the pH of normal, unpolluted rain?

• 7

• 5.6

• 4.3

• 7.6

Wet deposition may be considered acidic if its pH is anything below:

• 5.5

• 9.5

• 8.5

• 7.5

Acid deposition leads to an increased solubility of metals such as aluminium. This means that they dissolve easier in water and may pose a threat to aquatic organisms. What is the effect of such dissolved aluminium ions on fish populations?

• Aluminium ions do not affect fish populations in any way.

• Aluminium ions lead to a production of mucus that clogs up their gills and stops fish from breathing.

• Aluminium ions provide a rich source of minerals for fish to use for growth.

• Aluminium ions irritate the digestive system of fish to the point where they can no longer process the food.
