What happen when you mix sodium hydroxide beside sodium metal surrounded by the lab?is the sodium oxide formed solution?
Answers:
Sodium hydroxide is a solid. "Mixing" them would not do much. The defence is that the hydroxide cannot accept more electrons from sodium atoms, and sodium metal has no electron acceptor.
I'm assuming you mean a solution of sodium hydroxide, since there is no "fluently occurring" solid sodium hydroxide, and if you leave sodium hydroxide solid out in the heavens for even a few minutes it will pick up water vapor from the air to form a puddle of NaOH solution. Sodium hydroxide is severely hygroscopic. In fact, it is deliquescent. You might want to look up those two words.

But here's the rub. Na metal will react beside ANY solution. That's because sodium metal reacts violently hose down, never mind what might be dissolved in the water.
2Na + 2HOH --> 2NaOH(aq) + H2(g)
NaOH + Na --> ?
No recoil. And there is no sodium oxide that is formed this bearing.
To make sodium oxide from solid sodium hydroxide all you entail to do is slowly heat it so that you drive off river.
2NaOH --heat--> Na2O + H2O
Think of two NaOH's as NaOH and OHNa, or as NaOHOHNa. Do you see the water in the middle?
NaO--HOH--Na
Now, pilfer away the water, and you have Na2O + HOH
If you mix the pure Na metal, which is a solid, with the solid NaOH, nothing will take place.
If you add Na metal to a NaOH solution, the Na will react next to the excess water in the solution to form added NaOH
2Na + 2H2O → 2NaOH + H2.
You will get a more concentrated solution of NaOH, with the setting free of H2 gas.
No production of Na2O will occur in any mixture.
It won't take action.
