Explanation

White vitriol is the historical name for zinc sulfate crystals (ZnSO4·7H2O), which are white and crystalline in appearance. It's not zinc nitrite, calcium sulfate, or lead sulfate - those are different chemical compounds with different properties and uses.

AI explanation

White vitriol is the traditional name for zinc sulphate crystals (ZnSO4), historically classified alongside other 'vitriols' like blue vitriol (copper sulphate) and green vitriol (ferrous sulphate), each named partly for their appearance. Zinc sulphate crystals appear white/colorless, distinguishing this compound from its colored vitriol counterparts.
