• Indicator

Compounds that produce negative hydroxide ions (OH-) when dissolved in water.

• Acid
• Base
• Litmus
• Indicator

Which of these is not a property of acids?

• can conduct electricity
• reacts with metals
• sour taste
• bitter taste

Which of these is not a property of bases?

• can conduct electricity
• feel slippery
• sour taste
• bitter taste

Which of these do acids and bases both have in common?

• Both react with metals to form hydrogen gas
• Both conduct electricity
• Both taste sour
• Both taste bitter

Why can acids conduct electricity?

• Acids don't conduct electricity, only bases do.
• Acids become metallicized in water which allows for electrical conduction.
• When acids dissolve in water the solution consists of charged particles.

What happens when acids react with metals?

• The reaction produces helium gas.
• The reaction produces chlorine gas.
• The reaction produces a base.
• The reaction produces hydrogen gas.
