Homework Statement

Explain why sodium azide has a lower solubility than hydrazoic acid in hexane.

Homework Equations

The Attempt at a Solution

How to determine the solubility of solution in organic compounds?

Thankyou

 

[Borek]

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

 

[elitewarr]

But both NaN3 and HN3 are ionic compounds.

 

[Borek]

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

Well, it is quite a strong acid.

Comparable with acetic if memory serves me well.
