Suppose a chemist Compare the prepares an aqueous solution of ammonium nitrite (NHNO). a. What specles will be present in that solution? b. For each species present in the solution, indicate whether it will behave as an adid, a base, or neither Since NHe" is an acid and NO: is a base, will a solution of NHNO: be neutralP Hint: is NH a better acid than NO2 is a base? c. Compare the KG of NHH (calculated in question 5) with the Ks of NOr (calculated in question 7) Will NH NO: (aq) be acidic, basic, or neutral? Explain your reasoning So, to predict whether an oqueous solution of a salt is acidic, basic, or neutral, one must consider the ions present, and how eoch ion behaves in solution 9. Fill in the table below, as illustrated by the example in the first raw. Salt Cation Cation behavior Anion Anion behavior Salt behavior NaNO: Na Caco NHNO None Basic Basic

Explanation / Answer

7.Ionization of HNO2 in water is given by:

HNO2 --> H+ + NO2-
Ka = 4.3x10^-4 = [H+][NO2-] / [HNO2]

For a weak acid (HA) and its conjugate base (A-),

Ka x Kb = Kw = 1.0 x 10^-14 at 25 C.

Kb = Kw / Ka = (1.0 x 10^-14) / (4.3 x 10^-4) = 2.3 x 10^-11
