При какой температуре происходит реакция при нагревании диоксида марганца и концентрированной серной кислоты?
Reply #22015-07-19
При нагревании марганцита (диоксида марганца) с концентрированной серной кислотой образуется кислород. Уравнение реакции: 2MnO2 + 2H2SO4 → нагрев → 2MnSO4 + 2H2O + O2↑. Конкретная температура, при которой происходит реакция, не указана в большинстве источников. Извините
