Zn (s) + 2HCl (ac) ---> ZnCl2 (ac) + H2 (g)

El zinc se oxida y el hidrógeno se reduce. HCl es el agente oxidante mientras que Zn es el agente reductor.

2Na (s) + H2SO4 (ac) ----> Na2SO4 (ac) + H2 (g)

El Na se oxida y el hidrógeno se reduce. El ácido sulfúrico es el agente oxidante, mientras que el sodio metálico es el agente reductor de tge.

Ca (OH) 2 (ac) + H2CO3 (ac) ------> CaCO3 (s) + 2H2O (l)

Esta no es una reacción redox ya que no hay cambios en el número de oxidación de izquierda a derecha.
