Coin Test

During class, the chemistry professor was demonstrating the properties of various acids. "Now I'm dropping this silver coin into this glass of acid. Will it dissolve?"

"No, sir," a student called out.

"No?" queried the professor. "Perhaps you can explain why the silver coin won't dissolve."

"Because if it would, you wouldn't have dropped it in."
