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.

This is аn оptiоnаl extrа-credit questiоn. Answer correctly and get extra 5 points to be added to your final exam's score (if your score is lower than 105 points). In the graph, assume that B = 30 and D = 12. Suppose this market is closed to international trade (no trade). Given the information above: Calculate consumer surplus and producer surplus by showing your work! Suppose that now Wonderland enters the international market for sweaters (with trade), where one t-shirt now costs $15. Calculate the new values of consumer surplus and producer surplus by showing your work! Based on your calculations, who benefit and who lost (consumers or producers) when Wonderland entered the international market? Justify your answer!
