ELI5: why doesn't acid melt a glass container?
gpt
Some acids do. Hydrofluoric acid, for example, will eat through glass and can be used for glass etching. Other acids can break down glass under certain conditions. A Material Safety Data Sheet (MSDS) would list the exactly how a chemical should be stored.

Most acids, however, do not react with glass. Most substances, in fact, do not react strongly with glass. This is because the molecules that make up glass are so tightly bound that they are unable to trade or combine electrons with other substances. Glass is essentially a "closed" system.
