Ladeira Posted June 28, 2008 Posted June 28, 2008 It's just a curiosity. When the hydrogen ignites during the explosive reaction Na + H2O* * 2Na + 2H2O --> 2NaOH + H2 Can the Na that didn't react yet, react with O2 of the fire? 4Na + O2 --> 2Na2O And produce sodium oxide which would fall on water and producce NaOH? I remember I've put it in a Chemistry Lab Report and the teacher did not understand why did I 'invent' it... Can't it happen?
swansont Posted June 28, 2008 Posted June 28, 2008 What are the enthalpies of formation for those reactions/products?
Ladeira Posted June 29, 2008 Author Posted June 29, 2008 I'm sorry, I don't have enough knowledge to answer about the enthalpies =\
YT2095 Posted June 29, 2008 Posted June 29, 2008 yes, sodium will burn in air quite nicely when heated (as generated by the reaction with water). 1
John Cuthber Posted June 29, 2008 Posted June 29, 2008 The flame is typically yellow due to the presence of sodium so I think it's fair to assume that at least some of the sodium vapour burns. 1
Ladeira Posted June 30, 2008 Author Posted June 30, 2008 Thanks. That was my doubt ;D Now it isnt anymore.
