What are some of the uses for sodium oxide?

Curtis Evans  Follow

Sodium oxide is an ionic compound, composed of oppositely charged ions - positively charged metal cation and negatively charged non metal anions. The cation here is Na+ while anion is O(2-). As it is a neutral compound with a overall 0 oxidation state, we need to balance the charges, so the formula is Na2O, where the 2(+1) + (-2) = 0

Sodium Oxides’ main use is in the production of glass. Sodium oxide is generally makes up around 15% of glass chemical composition. It lowers the temperature at which silicon dioxide (70% glass composition) melts at. This makes it cheaper and more efficient to produce glass as it requires less energy input from the manufacturer.

Sodium Oxide ( Na2O) react vigorously with water and forms Sodium Hydroxide ( NaOH). Thus it is an Exothermic Reaction.

Chemical Reaction: Na2O(s) + H2O(l) 》2NaOH(aq)

Not going to length here. Just google Nurdrage videos on sodium preparation. It can be done but be mindful that it is difficult and quite dangerous.

For this kind of problems, you really need to be familiar with the usual oxidation states of atoms. Sodium has a usual oxidation state of +1 while oxygen (where oxide comes from) has a usual oxidation state of -2.

Na+ O2–

To write the formula, we do the “criss-cross” method, that is, the charge of the cation becomes the subscript if the anion. Likewise, the charge of the anion becomes the subscript of the cation. Hence for sodium oxide, the formula is Na2O. Take note that weEno longer have to explicity show that O has a subscript of 1.

Sodium Oxide - Na₂O.

Reason - Sodium has +1 oxidation number and oxygen has -2 oxidaton number.

Don't get confused, by sodium peroxide (Na2O2) and sodium superoxide (NaO2). Peroxide is -1 and superoxide -1/2.

Sodium oxide is Na₂O. Each sodium atom has a valence of +1, and the oxygen atom has -2.
