Redoxní reakce
Je následující reakce redoxní?
\( \textrm{Cu} + \textrm{O}_2 → \textrm{CuO} \)
\( \textrm{Cu}^{0} + \textrm{O}_2^{0} → \textrm{Cu}^\textrm{I}\textrm{O}^\textrm{−II} \)
\( \textrm{Cu}^{0} + \textrm{O}_2^{0} → \textrm{Cu}^\textrm{II}\textrm{O}^\textrm{−I} \)
\( \textrm{Cu}^{0} + \textrm{O}_2^{0} → \textrm{Cu}^\textrm{II}\textrm{O}^\textrm{−II} \)
\( \textrm{Cu}^{0} + \textrm{O}_2^{0} → \textrm{Cu}^\textrm{II}\textrm{O}_2^\textrm{−II} \)
Urči si oxidační čísla látek v reakci. Pokud se číslo zvyšuje, tak se rovná o oxidaci, pokud snižuje, tak je to redukce. Prvky mají oxidační číslo 0.
