There is now considerable concern over the use of many commercially available cleaning products. Most are highly toxic and harmful to the environment. However, there are numerous nontoxic acids and bases that can be used instead, which are common to most households.
Research the effects that commercial cleaning products have on the environment and what some of the non-toxic acid and base alternatives are. Try comparing how well a natural product works versus a commercial one that is sold for the same use.

You have probably seen examples of qualitative analysis while watching forensics shows on television. The investigators spray a liquid they call Luminol on a floor then shine ultraviolet light on it in a darkened room. If hemoglobin is present, it will fluoresce (glow). Also, an investigator might have swabbed a spot that is suspected to contain human blood. They drop a liquid on the swab and if it turns blue, they have evidence of human blood.

Police officers who suspect a person of drunk driving will ask them to take a Breathalyser™ test by blowing into a small hand-held device. This device estimates a driver’s blood alcohol concentration (BAC), which is based on a colour change that occurs when alcohol in the driver’s breath reacts with an acidic aqueous solution of potassium dichromate. What is the balanced equation for this reaction and why are stoichiometry calculations important? Research the answers to these questions and develop a diagram illustrating how the Breathalyser™ device works. Present this information as a poster. You may also want to include some statistics such as what the BAC legal limit is for driving in Alberta, and how many people are killed or injured due to drunk driving every year.

In 1997, representatives from Canada and more than 160 other countries met in Kyoto, Japan, to draft the Kyoto Protocol. They were attempting to address the problem of global warming caused by greenhouse gas emissions. Check the Internet for the latest information on Canada’s progress in meeting its Kyoto goals.

Voltaic cells are named after the Italian physicist Count Alessandro Giuseppe Antonio Anastasia Volta (1745–1827), who built the first chemical batteries. These cells are also called galvanic cells, after the Italian physician, Luigi Galvani (1737–1798). How did Galvani “discover” electrical cells while dissecting frog legs? How did Galvani’s and Volta’s interpretation of these observations differ?

Battery makers have been challenged to make batteries smaller, lighter, longer lasting, and more powerful. In March 2003, Dalhousie University established a Research Chair in Battery and Fuel Cell Materials. The university’s new laboratory is one of the few in the world equipped to use a new mode of research developed in 1995, called combinatorial materials synthesis (CMS). CMS rapidly shortens the time needed to test new combinations of materials by uncovering thousands of distinct compositions in a single experiment. Chief researcher Jeffery Dahn is applying CMS methods to improve the safety of lithium-ion batteries and produce cells large enough to power electric vehicles. How does CMS allow for the testing of so many materials at one time?

To remember the sign of the charge on the cathode in the two different types of cells (voltaic cells versus electrolytic cells), remember that electrons always leave the cathode and a reduction half-reaction occurs there. In a voltaic cell, the spontaneous chemical reaction “pulls” the electrons off the cathode leaving it positively charged. In an electrolytic cell, the external source of electrical energy “pushes” electrons onto the cathode making it negatively charged. This negatively charged cathode then “pushes” electrons onto the compound in solution, causing a reduction half-reaction to occur.
