Acid Base Practice

Which statement is true?

• Acids start with H and bases end with OH
• Acids start with OH and bases end with H
• Acids end with H and bases start with OH
• Acids end with OH and bases start with H

A strong acid:  

• completely dissociates in water
• partly dissociates in water
• doesn't dissociate in water
• has a really high pH

Name the correct definition of an acid and a base:  An acid ionizes to yield hydrogen ions (H+) in aqueous solution; a base ionizes to yield hydroxide ions (OH–) in aqueous solution.

• Lewis definition
