Chapter 4 Practice Worksheet: Reactions in Aqueous Solutions

Name: __KEY_____ Section: _____ Chapter 4 Worksheet Spring 2007 page 1 of 4 Chapter 4 Practice Worksheet: Reactions in Aqueous Solutions 1. List the three general classes of chemical Reactions : precipitation, acid-base neutralization, and redox Reactions 2. How can you identify each of the three reaction types above ( , what characteristic defines each one?)? Precipitation Reactions have solid products, also all reactants and products are ionic compounds; Acid-base Reactions react an acid with a base to produce a salt (ionic compound) and water; Redox Reactions result in a change in oxidation numbers of two species.

Redox reactions result in a change in oxidation numbers of two species. ... Decomposition (one compound decomposes, usually with heat, to give off a gas and another substance); Single-replacement (one element and one compound react to give one element and one compound) 15. For the following redox reactions, identify the species being oxidized ...

In this class we will provide the products for combination and decomposition reactions with either words or the formulas. However YOU must write the product formulas for combustion, acid base, single and double replacement reactions yourself! That is what makes this chapter so hard and probably this is the hardest chapter of the course.

These reactions yield products that are unfavorable to agriculture and aquaculture. Their reduced species are often more toxic than the oxidized species: For example nitrite NO2-is more toxic than NO3-, (H2S) is more than SO42-and Fe2+, Mn2+ can cause phytotoxicity in rice paddy.
