# Extra-Credit: The pH of the salt of a weak acidA nitrous solution, (HNO2, K, = 4.60x10-), is titrated with NaOH to reach theequivalence point making an aqueous sodium nitrite (NaNO2) solution%3DWrite out the net ionic equation for the neutralization of nitrous acid (HNO2) withhydroxide (OH) showing all appropriate phases and charges if anyAfter the titration we are left with sodium acetate and water. Write out the net ionichydrolysis reaction for the nitrite ([NO,]) with water including all phases ([aq),(1)etc) and chargesNOz (aq)+ H200Calculate the numerical value for equilibrium constant K, for the above hydrolysisreaction (Assume Kw = 10-14)%3DIf the sodium nitrite (NaNO,), solution is 0.50M at the equivalence point, what is thepH of the solution at the equivalence point? [OH]q =%3D%3DThe pH at the equivalence point pH =Is the resultant solution acidic, neutral or basic at the equivalence point?
