1. The problem statement, all variables and given/known data Soldium azide, NaN3 is sometimes added to water to kill bacteria. Calculate the concentration of all species in a 0.010 M solution of NaN3. The Ka value for hydrazoic acid, HN3 is 1.9X10^-5. 2. Relevant equations 3. The attempt at a solution I'm sort of confused because in the beginning i know that i have to separate NaN3 into its component elements..so in this case..NaN3-->Na+N3? or is it NaN3-->Na+3N?
