• Always add acid to water- never add water to acid. Sulfuric acid (H₂SO₄) reacts very exothermically with water. This reaction produces a substantial amount of heat.
• Potassium hydroxide reacts with aluminum to produce hydrogen gas which is very flammable.
• Ethanol is very flammable. Keep it away from the hot plates and burners!
• Potassium hydroxide and sulfuric acid are dangerous when directly inhaled. They are also very caustic: they will burn you if they come in contact with your skin. If this happens rinse thoroughly with water, and have someone get a TA.
• As always, be aware of your surroundings and others in the lab, and please ask a TA if you have any questions!
