What happens if a container is not sealed?
If the container is not well-sealed, some of the acid (which has its own vapor pressure independent of the solvent) will escape over time. The acid reacts with something to which it is exposed in its storage environment.
Is HCl a gas?
some acids like HCl, for example, are a gas dissolved in water. The HCl will be present in the vapor space over the liquid acid. If the container is open, HCl gas will escape and the acid solution will therefore become diluted over time. Some organic acids would also be affected in this way.
Is H2SO4 ionized?
BUT, concentrated sulfuric acid is hardly dissociated at all - there are few free hydrogen ions. As it becomes diluted, it becomes more ionized - you mi. Continue Reading. some acids like HCl, for example, are a gas dissolved in water.
Is sulfuric acid hygroscopic?
Sulfuric acid, H2SO4, is hygroscopic. It will absorb moisture from the air. So if a container of H2SO4 is left open, it will become more diluted over time. BUT, concentrated sulfuric acid is hardly dissociated at all - there are few free hydrogen ions.
Does HF dissolve glass?
