If you've ever been asked "is this a strong acid or a weak acid?" on an exam, the answer comes down to one idea: how completely the acid or base reacts with water. In this guide, we'll cover the difference between strong and weak acids and bases, the short list of strong ones you need to memorize, common weak acids and bases with their Ka and Kb values, what happens when you mix them, and why bleach is a weak base. Strong vs. Weak Acids and Bases: The Key Difference An acid i

Need to review concepts in hybridization? Have a look at this new whiteboard lecture to catch you up on everything dealing with hybridization (focusing only on sp, sp2, and sp3). This video lecture will show how we combine atomic orbitals and hybridize them to obtain bonding molecular orbitals in valence bond theory. Enjoy!
