Because a reactive metal displaces less reactive metal from its salt,& NaOH is a base.
What happens if burnt sodium is exposed to oxygen?
Sodium and Lithium react so rapidly with air and water, that they must be contained under oil. Sodium burns rapidly in air, releasing heat and light energy. If you explore around YouTube for videos of this reaction, some may explode. This is the light and heat energy being given off. Equation: 4Na + O2 --> 2Na2O
Which end of the water molecule is attracted to the sodium ion?
Since water is a slightly polar molecule (the hydrogen end being slightly positive and the oxygen ends being slightly negative) the positively charged sodium ion (Na+) will be attracted to the oxygen end of the water molecule.
