Question

Table A. Calculated and Measured pH's of Acid and Base Mixtures Complete the reaction table for the mixture of 10.0 mL of 0.10 M NH_4CI with 10.0 mL of 0.10 M NaOH below. (All entries should be in millimoles. Enter your answers to one decimal place.) Calculate the equilibrium concentration of NH_3. (Enter your answer to two significant figures.) [NH_3] =___M Which of the following describes the solution that was produced? (Select all that apply.) a solution containing a weak base and a strong acid a solution containing a weak acid and a weak base a solution containing a weak acid and strong base a solution containing a weak base and a strong base a solution containing only a weak acid a buffer a solution containing only a weak base a solution containing only a strong base a solution containing only a strong acid a solution containing a conjugate acid/base pair a solution containing a strong acid and a strong base

Explanation / Answer

         NH4+(aq)    +     OH^-(aq)   <====> NH3(aq) + H2o

initial          1                  1                0    

change           1                  1                1

final        1-1= 0                  0               1

concentration of NH3 = mmol/V in ml = 1/20 = 0.05 M

produced solution : solution containing only weakbase.
