Whаt is the pH оf а 0.050 M NH4Cl sоlutiоn аt 25 °C? The Kb for NH3 is 1.8x10-5. Enter only the final answer in the response box. Solution steps: Determine the hydrolyzing ion Determine the concentration of the hydrolyzing ion Determine the value of the equilibrium constant of the hydrolysis reaction (Kw=Ka.Kb) Write the hydrolysis reaction Fill the i.c.e. table with known information (initial concentration of the hydrolyzing ion) Label the unknown with “x” and fill the rest of the ice table Write the Ka or Kb expression for the hydrolyzing ion Substitute equilibrium concentrations in the i.c.e. table Check for the simplifying assumption Solve for “x” calculate pH or pOH using final concentration.
