1) Answer the following questions using the table below: Acid K. 6.31 x 10-5 Benzylammonium ion, C6H5CH2NH3* 4.47 x 10-10 1.35 x 10-3 1.00 x 10-7 Benzoic Acid, C¢H$CO2H Chloroacetic acid, CICH2CO2H Hydrogen Sulfide, H2S Nitrous Acid, HNO2 4.47 x 104 a) Which is the strongest acid? b) Which acid has the highest pH, and what is the chemical formula of the conjugate base? c) Write the reaction of nitrous acid (HNO2) acting as a BrØnsted-Lowry acid in water and write the K, expression. d) Nitrous acid will react in water according to the reaction you wrote in part (c). What is the predicted pH of a solution that is made by adding 0.050 moles of nitrous acid to 0.500 L of water? State any assumptions you make in arriving at a number. Ka is in the table above. e) How do you change the pH to increase the relative amount of nitrous acid in the solution? Think about Q and K. f) Write the full balanced reaction and the net ionic equation for aqueous nitrous acid reacting with aqueous NaOH, a strong base.
