Chemistry nerds are built different! The joke here is pure genius - the hydroxide ion (OH - ) is literally a "base" in chemistry, with that negative charge making it basic on the pH scale. So when someone asks why it's "so negative," they're accidentally making a chemistry pun about its negative charge, while the chad figure recognizes it's actually "based" (basic)! It's the perfect chemistry wordplay that works on multiple levels - negative ion, basic solution, and internet slang all in one beautiful chemical joke!
