Pour \u00e9viter que des carottes fraichement r\u00e2p\u00e9es deviennent noires en surface par oxydation, on les plonge dans du jus de citron.
\nSur l\u2019\u00e9tiquette d\u2019un flacon, un \u00e9l\u00e8ve lit : \u00ab Jus de citron : acide citrique 15 g pour 250 mL.<\/p>\n
Comment retrouver exp\u00e9rimentalement l\u2019indication port\u00e9e sur le flacon tout en respectant les consignes de s\u00e9curit\u00e9 ?<\/p>\n
