L'acide sulfurique pur est un liquide épais, incolore et inodore, qui se solidifie à 10 °C. [...] pendant l'ébullition, le liquide se dilue légèrement et l'on obtient un mélange azéotrope, bouillant à 320 °C, qui contient environ 98 % d'acide pur. C'est ce mélange qui constitue l'acide concentré du commerce; [...] L'acide sulfurique est un produit industriel fondamental [...]. Ses applications sont [...] extrêmement nombreuses [...]. Il constitue [...] l'électrolyte des accumulateurs.
