Question

Na-->NaO-->NaOH ?????

Answer 1

4Na+O2=2Na2O
Na2O+H2O=2NaOH

Answer 2

Yes, that is correct. When metallic sodium (Na) reacts with water (H2O), it forms sodium hydroxide (NaOH) and hydrogen gas (H2). The reaction proceeds in several steps:

2Na + 2H2O → 2NaOH + H2

At the first step, the sodium metal reacts with water to form sodium hydroxide and hydrogen gas. However, the intermediate product formed in this step is actually sodium hydroxide molecule with a sodium ion attached to it (NaO-):

Na + H2O → NaO- + H2

The NaO- then reacts with water to form the final product, sodium hydroxide:

NaO- + H2O → NaOH
