SUMMARY

Silicate glass, particularly borosilicate glass, is generally effective for dissolving various acids, with the notable exception of hydrofluoric acid. The discussion emphasizes that while all silicate-based glasses (SiO2) can be used in laboratory settings, their effectiveness can vary based on the specific acid and the desired outcome. For instance, dissolving coal in sulfuric acid versus hydrochloric acid yields different residues due to the distinct properties of these acids. Proper safety precautions are essential when handling concentrated acids, as they are corrosive and potentially toxic.

PREREQUISITES
  • Understanding of silicate glass properties
  • Knowledge of acid-base chemistry
  • Familiarity with laboratory safety protocols
  • Basic concepts of solubility and dissolution processes
NEXT STEPS
  • Research the properties of hydrofluoric acid and its effects on different glass types
  • Explore the differences in residues produced by various acids when dissolving organic materials
  • Learn about laboratory glassware specifications and their chemical resistance
  • Study the solubility rules for sulfates and chlorides in acidic solutions
USEFUL FOR

Chemists, laboratory technicians, and anyone involved in materials science or acid-base reactions will benefit from this discussion, particularly those working with glassware in chemical experiments.

Is there a certain borosilicate that resists all types well enough to dissolve rocks in them?

Are there reasons to dissolve rocks in different types of acids to get a different result? Dissolving coal in sulfuric vs hydrochloric for instance, would you get a different residue/result?

Thank you for any help assisting this noob.

Acids do have a common characteristic - they produce H+ when dissociating, and H+ is an oxidizing agent (mildly strong), but their other properties vary, which often makes one better for a specific task than others.

Silicate glass is in general good for all acids with an exception of hydrofluoric. That's an example of where the 'other properties' come into play.

Thank you for responding. I already have some borosilicate glassware, are you saying I just need specifically a silicate container?

No, I mean "any glass that is SiO2 based" - which in practice means all of them. Sure, there are differences, but as long as we are talking about laboratory glass (as opposed to "any glass container sold for general public") they shouldn't matter.

Disclaimer: all possible warnings about concentrated acids go here, they are dangerous, corrosive, some are especially toxic and they all require care/proper setup/proper hardware. To avoid the risk: learn the rules, play by them.

Counter ion makes a huge difference. Most sulfates are soluble as chlorides, but a lot of sulfates aren't soluble as chlorides (just to use your example?. This will affect solubility in acid if there isn't another dissolution pathway, i.e. hydrogen gas formation.

Dissolving or selectively dissolving or breaking up minerals may require specific mixtures of acids, at specific pressures and temperatures. Unless you are working exclusively with the good old and trivial limestone, the process is a far broader topic than just 'storage': especially if safety is properly accounted.

Take care.
