What is the pH of the 0.30 M NH_3/0.36 M NH_4CI buffer system. What is the pH after the addition of 20.0 mL of 0.050 M NaOH to 80.0 mL of the buffer solution? How would you prepare a liter of carbonate buffer at a pH of 10.10? you are provided with carbonic acid (H_2CO_3), sodium hydrogen carbonate (NaHCO_3), and sodium carbonate (Na_2CO_3). Look up Ka values. 100 mL of 0.010M nitrous acid (HNO_2) are titrated with a 0.10 M NaOH solution. Calculate the pH for (a) the initial solution (b) after 80 mL has been added (c) the equivalence point (d) after 105 mL has been added
