• Base: a molecule or entity that accepts a proton

Properties of Acids and Bases

• Acids: taste sour, turn litmus paper red, found in fruits
• Base: taste bitter, turn litmus paper blue, found in soaps

Reading PH

• Less than 7, the substance is and acid
• Greater than 7, the substance is a base
• Equal to 7, than it is neutral and most likely water.

Conductivity meter

• Used to see if the substance produces electricity
• If the light bulb lights up it is an electrolyte
• If the light bulb doesn't light up it is a nonelectrolyte

IDENTIFYING Acids & Bases

• Acid is a proton donor
• H+
• Bases accept protons
• OH-
