What is the pH of a 0.225 M KNO2 solution? The K_a for formic acid (HCO_2H) is 1.8 .10^{-4}. Given that Ka for HCN is 4.9 * 10^ 10 and K b for NH3 is 1.8 * 10^-5 at 25.0 degrees C, calculate Kb for CN and Ka for NH4+. Conjugate acid of HCO, A:Proton (H+)donar is Bronsted acid. 6) Consider the mixing of sodium hypobromite (NaBrO) into 2.00 of 0.25 M hypobromous acid (HBrO) to form a buffer solution (Ka of HBrO = 2.3 x 10-92 Assuming that no volume change occurs when the NaBrO is added, Calculate the number of moles of NaBrO need to be added into the solution to form buffer solution with pH of &8.20 ii, Calculate the
