    Re: solubility

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

    But both NaN3 and HN3 are ionic compounds.

    Re: solubility

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

    Re: solubility

    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.
