Acids and Bases Quiz

What is the Arrhenius definition of acids?

• Acids are substances that produce oxygen gas when mixed with water

• Acids are substances that do not react with water

• Acids are substances that produce hydroxide ions (OH-) in water

• Acids are substances that dissociate in water to produce hydrogen ions (H+).

What is the Arrhenius definition of bases?

• Substances that do not react with water at all

• Substances that dissociate in water to produce oxygen ions (O2-)

• Substances that dissociate in water to produce hydroxide ions (OH-)

• Substances that dissociate in water to produce hydrogen ions (H+)

What are the properties of acids?

• Acids have a sour taste, turn blue litmus paper red, and have a pH less than 7.

• Acids have a sweet taste, turn red litmus paper blue, and have a pH greater than 7.

• Acids have a bitter taste, turn blue litmus paper red, and have a pH greater than 7.

• Acids have no taste, do not affect litmus paper, and have a pH of 7.
