General Chemistry II Workshop 3: Acid-Base Equilibria (10 pts total) In today's workshop we will explore two classes of compounds known as acids and bases. Acids were first identified as compounds that taste sour while bases were first identified as compounds that feel slippery and taste bitter. Today there are 3 prevailing theories that define acids and bases. We will spend most of our time...
