Sodium azide has a lower solubility than hydrazoic acid in hexane

Click For Summary
SUMMARY

Sodium azide (NaN3) exhibits lower solubility in hexane compared to hydrazoic acid (HN3) due to differences in their ionic and non-ionic characteristics and the polarity of the solvent. While both compounds are ionic, hydrazoic acid, being a stronger acid, does not dissociate effectively in non-polar solvents like hexane. Sodium azide, as a salt, has limited solubility in non-polar environments, which further contributes to its lower solubility compared to hydrazoic acid.

PREREQUISITES
  • Understanding of ionic vs. non-ionic compounds
  • Knowledge of solvent polarity
  • Familiarity with acid strength and dissociation
  • Basic principles of solubility in organic solvents
NEXT STEPS
  • Research the solubility principles of ionic compounds in non-polar solvents
  • Study the dissociation behavior of strong acids in various solvent types
  • Explore the concept of solvent polarity and its impact on solubility
  • Investigate the properties of hydrazoic acid and its comparison with other acids
USEFUL FOR

Chemistry students, organic chemists, and anyone interested in the solubility behaviors of ionic compounds in non-polar solvents.

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.
