At what temperature does HCl condense?
Hydrogen chloride is a colourless gas of strong odour. It condenses at −85 °C (−121 °F) and freezes at −114 °C (−173 °F). The gas is very soluble in water: at 20 °C (68 °F) water will dissolve 477 times its own volume of hydrogen chloride.
What is the density of 15% HCl?
The specific gravity (density relative to the density of water) of hydrochloric acid solution is 1.18 g/mL.
At what concentration does HCl fume?
Hydrogen chloride acid is a colorless, corrosive, liquid that fumes in air at high concentrations of 25% or more, and becomes a hydrogen chloride gas forming dense white vapors due to condensation with atmospheric moisture. The vapor is corrosive, and air concentrations above 5 ppm can cause irritation.
What to do if you get HCl on your skin?
Skin Contact – If hydrochloric acid comes into contact with your skin, flush immediately with plenty of water for at least 15 minutes, and remove any contaminated clothing. In case of serious skin contact, use water, a disinfectant soap, and anti-bacterial cream. Seek immediate medical attention.

How do you make 2% HCl?
- 1M HCl: add 1mol/12M = 83 ml conc. HCl to 1L of water or 8.3ml to 100ml.
- 2M HCl: add 2mol/12M = 167 ml conc. HCl to 1L of water or 16.7ml to 100ml.

How do labs handle HCl?
Handling. Wear a chemical-resistant apron, chemical-resistant gloves and chemical splash goggles at all times when handling HCl to protect your eyes and skin. Concentrated hydrochloric acid is toxic if inhaled, so avoid breathing it in and always handle it while under a fume hood.
