Question:

1. Identify the Brönsted acid and base in the following reaction, and identify the conjugate base and acid formed. HSO3-(aq)
1. Identify the Brönsted acid and base in the following reaction, and identify the conjugate base and acid formed. HSO3-(aq) + CH3NH3(aq) ------ H2SO3(aq) + CH3NH2(aq) 2. Write the formulae for the conjugate acids of: 1. a) C2042: the oxalate ion. 2.b) C6H5NH2, aniline. 3.c)NH2OH, hydroxylamine. (Use above question as a guide for where to put the H.) 3. Calculate the molarity of OH' in solutions with the following concentrations of H30*: a) 0.020 mol LP b) 1.0 x 10-5 mol L-1 c) 3.1 mmol-L-1 4. A careless laboratory technician prepares 300.0 mL of 0.0175 M KOH(aq) and pipets 25.0 mL of the solution into a beaker. The beaker is allowed to stand in a warm place for a day before use, during which time some of the water evaporates and the volume is reduced to 18.0 mL. a) What would the pH of the solution as initially prepared have been? b) What will the actual pH of the solution be after evaporation? 5. Calculate the equilibrium concentrations of HNO2, H3O+ and NO2 at equilibrium if the initial conc. of HNO2 is 1.0 M. Calculate the pH and pOH. (K, for HNO2 is 5.1 x 104) HNO2(aq) + H2O(1)
