• They taste bitter

• They are corrosive (eat away at other materials)

• Can conduct electricity in a solution

Water and salt are formed when an acid and base react with each other. What is this called?

• Chemical

• pH scale

• Neutralization

• Dissolving

Water is the universal solute?

• True

• False

How are acids different from bases in a water solution?

• Hydrogen ions (H+) remain dissolved, but hydroxide ions (OH-) do not

• Acids form salts, but bases do not

• Acids turn litmus paper blue, while bases turn litmus paper red

• Acids form hydrogen ions (H+), while bases form hydroxide ions (OH-)
