Qualitative Analysis

Time Frame: Three weeks


By the end of this unit students will be able to do the following:

Overview of Unit

Demonstration: During class discussion students will start to investigate the properties of water that make it valuable to living things and most chemical reactions. Time will be spent having students investigate electrolytic solutions that can light a light bulb, run a clock, and glow in the dark. Students will be lead through discussion as to what they believe is causing the phenomena to appear. After listing several of their responses the teacher will start shifting their focus to target chemical energy. This discussion will lead back to the fundamental particles of the atom and focus on the electrons and the formation of ions. Students will be able to see first hand charged particles through demonstrations; the cathode ray tube and the Van de Graff generator. Students will experience physical changes that will help them detect chemical changes in solutions through qualitative analysis. Once the students have a grasp for how ions form and combine the testing needed to be done for the water sample can be explained.

Start Inorganic Nomenclature.

Reinforcement with plenty of homework.

At the beginning of the second week the introduction of the lab portion will happen . A systematic combination of ions is conducted using salt solutions and identifying precipitates.

Writing Formulas for Inorganic

Reinforcement with plenty of homework.
