I mistakenly put a sulfuric acid drain cleaner in my bathroom sink. Some of it spilled into the bathroom in my basement. I cleaned it up using baking soda, but I'm concerned if I missed any, whether it will still be acidic after it dries. Does sulfuric acid lose its acidity after it dries?




It reacted with the baking soda and is no longer sulfuric acid, but much safer sodium sulfate. If you're unsure, add more baking soda until it no longer fizzes. 


The remaining white powder is a mix of baking soda or $\ce{NaHCO3}$, and sodium sulfate, $\ce{Na2SO4}$. It safe to wipe up with a damp rag and fairly harmless to touch. Just avoid getting the powder in your eyes.
