6.4 Acid deposition

Experiments

Here are experiments our science specialists have selected to support the IB* topic.

Acid Rain

Experiment #18 from Biology with Vernier

In this experiment, you will

  • Measure pH.
  • Study the effect of dissolved CO2 on the pH of distilled water.
  • Study the effect on pH of dissolving H2SO4 in various waters.
  • Learn why some bodies of water are more vulnerable to acid rain than others.

Inquiry

Soil and Acid Rain

Experiment #12 from Investigating Environmental Science through Inquiry

In the Preliminary Activity, you will use a pH Sensor to measure the pH of acid rainwater. You will then filter the acid rainwater through soil, collect the resulting filtrate, and measure the filtrate pH as you determine the soil’s influence on acid rainwater pH.

After completing the Preliminary Activity, you will first use reference sources to find out more about acid precipitation, soil pH, and soil buffering capacity before you choose and investigate a researchable question.

Inquiry

The Effect of Acid Deposition on Aquatic Ecosystems

Experiment #31 from Investigating Environmental Science through Inquiry

In Part I of the Preliminary Activity, you will use a pH Sensor to monitor pH as dilute sulfuric acid is added drop wise to a water sample.

General water hardness is related to the dissolved minerals in the water. In Part II of the Preliminary Activity, you will use a Conductivity Probe to determine the conductivity of water from the same source.

After completing the Preliminary Activity, you will first use reference sources to find out more about acid deposition before you choose and investigate a researchable question dealing with acid deposition.
