CHAPTER 25 VOCABULARY

NAME:_________________________

1. acid-_any substance that produces hydrogen ions in a water solution

2. base-_ any substance that forms hydroxide ions in a water solution

3. buffer- solution containing ions that react with added acids or bases and minimize their effects on pH

4. hydronium ion- form when an acid dissolves in water and H+ ions interact with water

5. indicator- organic compound that changes color in acids and bases

6. neutralization- chemical reaction that occurs when the H3O ions from an acid react with   				      theOH ions from a base to produce water molecules

7. pH- measure of the concentration of hydronium ions in a solution using a scale ranging from 0  		to 14, with 0 being the most acidic and 14 being the most basic

8. salt- compound formed when negative ions from an acid combine with positive ions from a         	            base
9. soap- organic salts with non-polar, hydrocarbon ends that interact with oils and dirt and polar   	    		  ends that helps them dissolve in water

10. strong acid- any acid that ionizes almost completely in a solution

11. strong base- any base that ionizes completely in a solution

12. titration- process in which a solution of known concentration is used to determine the 			          concentration of another solution

13. weak acid- any acid that only partially ionizes in a solution

14. weak base- any base that does not ionize completely in a solution
