What happens when you add the element sodium to water?
Sodium reacts violently with water.
2Na(s) + 2H2O(l) --> 2NaOH(aq) + H2(g) + heat
The heat of the reaction will ignite the H2 gas and make it explode, producing more heat.
H2(g) + O2(g) --> H2O(g) + heat
If you still have unreacted sodium, the heat from the explosion will cause sodium to ignite and explode.
Na(s) + O2(g) --> Na2O2(s)
Na2O2 is a peroxide that contains O22-, rather than the O2- ion you normally see.
What happens when you add sodium to water?
It reacts VERY explosively, in the US i believe it is impossible to own or purchase pure sodium without proper licensing... it is so volatile that it must be stored in kerosene oil so that the water in air cannot cause it to combust. Sodium is also used as a base element for many explosive compounds.
Will adding sodium to chloride in water give salinity of the water?
Salinity (or 'saltiness') is due to the compound sodium chloride, written NaCl, and adding more of this will increase the salinity. However never add metallic sodium to water, it produces a violent and dangerous reaction. So when you say 'adding sodium to chloride' I'm not sure what you mean. The compound sodium chloride is just cooking salt and quite harmless and you can add as much of that as you like, but sodium as an…
Is it impossible for an element to replace atoms of anothe element in a compound?
No. In a displacement reaction, that is exactly what happens. If an element low down in the reactivity series is in a compound, and you add an element that is higher placed in the reactivity series. The more reactive element will displace the less reactive element in the compound. Example: Copper Sulphate - Copper is low in the reactivity series and is in a compound Sodium + Copper Sulphate - Sodium is higher in the…
