12. What is the % ionization for a 0.400M solution of HN3 (hydrozoic acid)? Ka = 1.9 x 10-5

Balanced equation: HN3 (aq) H+ (aq) + N3- (aq)

Now we will construct an I.C.E. grid for the initial, change, and equilibrium concentrations.

What are the inital concentrations of each of the species?

a) 0M, 0.400M, 0M
b) 0.400M, 0.400M, 0.400M
c) 0M, 0M, 0.400M
d) 0.400M, 0M, 0M
