Acids and Bases

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
• Arrhenius definition
• Bronstead-Lowry definition
• Jill Thompson definition

Who defined an acid as an electron-pair acceptor and a base as an electron-pair donor?

• Arrhenius
• Bronstead and Lowry
• Lewis
• Prince... too soon?

What is the range of pH values in an acidic solution?

• 0-7
• 7-14
• 15-239058204958
• pH = 7

What methods can you use to measure the pH of a solution?

• Observing color or clarity
• Measuring mass or volume
• Measuring density or electrical conductivity
• Using acid base-indicators or pH meters

In a neutralization reaction, what are the products of a reaction between an acid and a base?

• Another acid and base
• Carbon dioxide and a salt
• Water and a salt
• Either two acids or two bases

Who defined acids and bases this way:  An acid donates a hydrogen ion in a chemical reaction.  

• Bronstead-Lowry
• Lewis
• Arrhenius
