This case was developed for use in the first semester of a sophomore organic chemistry laboratory to illustrate how a combination of techniques is usually required in the identification of chemical compounds. It involves a murder mystery with a forensic twist. Students are told that two bodies have recently been recovered from two different lakes. Due to a mix-up at the morgue, the coroner's office is unable to determine which body came from which lake. The students' task is to develop a methodology to solve this mystery as well as determine whether the deaths were the result of murder or mishap. The case could also be used in instrumental analysis courses or adapted for a non-majors course in the general education curriculum.

In this activity, students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also learn several things that engineers are doing to reduce the effects of acid rain.

How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

Acid rain occurs when the pollutants that come from immobile sources such as smokestacks, power plants, and mobile sources such as cars rise up into the clouds and fall back to earth as contaminated rainfall. The rain becomes acidic because of gases which dissolve in the rain water to form various acids. Rain is naturally slightly acidic because of the carbon dioxide dissolved in it.  Acidic water contains an excess of hydrogen ions. Absolutely pure water contains equal numbers of acidic and basic ions (H+ and OH-). This gives rain a pH of around 5.0. Acid rain is formed by the reaction of rain water to a combination of various gases. Acid rain has some rather disastrous consequences on human, plant and animal life. Kindly find the attachments for more knowledge about the acid rain.
