I am trying to dilute concentrated sulfuric acid, and am having an argument with one of my advisors. What material (as in a beaker) can I perform the dilution: glass or plastic? She says it has to be plastic because acids etch glass. I think that because the sulfuric acid is stored in a glass bottle, then I can dilute it in a glass beaker. And I know the whole thing about “add acid to water”... I’m hoping there are some chemists out in the collective.
