Acids and Bases

An Arrhenius acid contains

• hydrogen that does not ionize

• hydrogen that ionizes to form hydrogen ions

• oxygen that ionizes to form hydroxide ions

• oxygen that ionizes to form oxygen ions

Acids taste

• sweet

• sour

• bitter

• salty

The traditional definition of acids is based on the observations of

• Bronsted and Lowry

• Lewis

• Arrhenius

• Mendeleev

Arrhenius theorized that an acid is a chemical compound that

• increases the concentration of hydrogen ions when dissolved in water

• increases the concentration of hydroxide ions when dissolved in water

• decreases the concentration of hydrogen ions when dissolved in water

• decreases the concentration of hydroxide ions when dissolved in water

Aqueous solutions of bases

• contain only two different elements

• carry electricity

• have very high boiling points

• cannot be prepared
