Dobrý den, už nějakou dobu tápu nad zadáním příkladu v chemii, vůbec nevím, co mám s ním dělat, můžu vás požádat o pomoc? (ps: s hustotou jsem to vypočítala, bohužel prý hustotu používat nemáme...)
kolik ml 0,01M roztoku manganistanu spotřebujeme na úplnou oxidaci 15ml roztoku 0,02 M železnaté soli
(vlevo-protony+manganistanový ion+železnatý ion
vpravo - železitý+manganatý ion + H2O)
