Acids and Bases Quiz2

What are the properties of acids?

• Acids have a salty taste, turn red litmus paper red, and react with metals to produce helium gas.

• Acids have a sweet taste, turn blue litmus paper blue, and react with metals to produce oxygen gas.

• Acids have a sour taste, turn blue litmus paper red, and react with metals to produce hydrogen gas.

• Acids have a bitter taste, turn red litmus paper blue, and react with metals to produce carbon dioxide gas.

What are the properties of bases?

• Bases donate protons or accept pairs of electrons.

• Bases accept protons or donate pairs of electrons.
