Question

what happens when sodium peroxide dissolves in water n sodium metal is dipped in water?

Answer 1

Hey folk....


Below is the balanced chemical reaction:

2Na2O2 + 2H2O --------------> 4NaOH + O2

When sodium metal is dipped in water:
Sodium reacts violently with water, because amount of released energy is more than the ignition temperature of hydrogen gas liberated, so hydrogen gas catches fire.

Na + H2O -------> NaOH + H2

Thank you
