Hydrochloric Acid

Concentrated or diluted HCl has to be handled carefully because it burns. Keep it in glass bottles and away from metal stuff.

Safety glasses, gloves, and old clothes are good to wear, not short-sleeved shirts, shorts, or sandals. The fumes can knock you out! When acid spills on you, rinse it with water. Use a bandage for small burns. With serious burns, you just might think about goint to a doctor or you just mite die!!!!

In the lab when diluting, pore the acid into the water. In titration, use a burro to measure what HCl you need for the sodium hydrocarbonate. That’ll help you measure the base.

To get rid of leftovers, neutralize and flush it. If you spill HCl, use baking soda.
