CN−(aq)+H2O(I)→HCN(aq)+OH−(aq) This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Zumdahl, Donald J. Because the activity of water is 1: KaKb = (H3O+) + (OH-) = Kw = 10-14 Where Kw is the equilibrium constant water. CN- + H2O HCN + OH- Here, CN- accept H+ and thus HCN is formed. Zellner and B. The rate coefficient value was not changed. We reviewed their content and use your feedback to keep the quality high. This relationship allows the calculation of either Ka or Kb if the other is known by: pH + pOH
a) HCN (donates a proton to H 2 O) is acid and H 3 O + (differs from H 2 O by one proton) is Conjugate Acid, H 2 O (accepts a proton from HCN) is Base CN-(differs from HCN by one proton) is Conjugate Base. We reviewed their content and use your feedback to keep the
