Important – Read Before Using Slides in Class Instructor: This PowerPoint presentation contains photos and figures from the text, as well as selected animations and videos. For animations and videos to run properly, we recommend that you run this PowerPoint presentation from the PowerLecture disc inserted in your computer. To run the animations on these slides please click on the icon on each still. If you prefer to customize the presentation or run it without the PowerLecture disc inserted, the animations and videos will only run properly if you also copy the associated animation and video files for each chapter onto your computer. Follow these steps: 1. Go to the disc drive directory containing the PowerLecture disc, and then to the “Media” folder, and then to the “PowerPoint_Lectures” folder. 2. In the “PowerPoint_Lectures” folder, copy the entire chapter folder to your computer. Chapter folders are named “chapter1”, “chapter2”, etc. Each chapter folder contains the PowerPoint Lecture file as well as the animation and video files. For assistance with copying the slide and video files, please visit our Technical Support at www.cengage.com/support or call (800) 423-0563. Thank you.

8 Aqueous Solutions: An Introduction Classification of solutes strong electrolytes - conduct electricity extremely well in dilute aqueous solutions Examples of strong electrolytes 1. HCl, HNO 3 , etc. strong soluble acids 2. NaOH, KOH, etc. strong soluble bases 3. NaCl, KBr, etc. soluble ionic salts ionize in water essentially 100%
