1. Acidic and Basic Solutions CHAPTER 8, SECTION 3

2. When dissolved in water, these substances RELEASE hydrogen ions (H + ) which bond with the water (H 2 O) to produce hydronium ions (H 3 O - ) ACID

3. When dissolved in water, these substances ACCEPT hydrogen ions (H + ) from water which produces hydroxide ions (OH - ) BASE

5. Measure of how acidic or basic a solution is, ranging in a scale from 0 to 14; also refers to the ‘potential of Hydrogen’ pH

6. A pH of 0-6.9 is considered… ACIDIC (pH of 0 is strongest)

7. A pH of 7.1-14 is considered… BASIC (pH of 14 is strongest)

8. A pH of 7 is considered… NEUTRAL

17. Compound that changes color at different pH values when it reacts with acidic or basic solutions INDICATOR

18. Interaction that occurs between acids and bases in which the properties of each are canceled out by the other NEUTRALIZATION

19. H3O-H3O- * Produced when acids release/give up H+ ions to water Acid + H 2 O → Acid + H 3 O - HYDRONIUM ION

20. OH - * Produced when bases accept/gain H+ ions from water Base + H 2 O → Base + OH - HYDROXIDE ION
