Sodium azide has a lower solubility than hydrazoic acid in hexane

Click For Summary

Discussion Overview

The discussion revolves around the solubility of sodium azide compared to hydrazoic acid in hexane, focusing on the factors influencing solubility in organic solvents, particularly the roles of ionic versus non-ionic characteristics and solvent polarity.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions how to determine solubility in organic compounds.
  • Another participant suggests considering the differences between ionic and non-ionic compounds and the polarity of the solvent.
  • A participant asserts that both sodium azide (NaN3) and hydrazoic acid (HN3) are ionic compounds.
  • There is a query regarding the strength of hydrazoic acid and its dissociation in a non-polar solvent.
  • One participant believes that while hydrazoic acid is a strong acid, it may not dissociate in a non-polar solvent due to its polar nature, while sodium azide, being a salt, might dissolve in non-polar solvents.
  • Another participant compares the strength of hydrazoic acid to acetic acid, suggesting it is quite strong.

Areas of Agreement / Disagreement

Participants express differing views on the solubility of sodium azide and hydrazoic acid in hexane, with no consensus reached on the reasons for their solubility differences.

Contextual Notes

Participants discuss the implications of ionic versus non-ionic characteristics and solvent polarity, but the discussion does not resolve the complexities of these factors in relation to solubility.

Think in terms of ionic vs non-ionic compounds and solvent polarity.
 


But both NaN3 and HN3 are ionic compounds.
 


How strong acid is HN3? Is it dissociated, especially in non polar solvent?

Well, it is quite a strong acid. However, what i believe is that it will not dissociate in non polar solvent as it is polar. But for sodium azide, it is a salt isn't it? Unless it is non-polar? Then it will dissolve in non-polar solvent?

Thank you

Comparable with acetic if memory serves me well.
