3. You are asked to make a buffer solution with a pH of 3.40 by using 0.100 M HNO, and 0.100 M NaOH (aq). a. Explain why the addition of 0.100 M HNO2 to 0.100 M NaOH(aq) can result in the formation of a buffer solution. Include the net ionic equations for the reaction that occurs when you combine HNO2 (aq) and NaOH(aq). Determine the volume, in ml, of 0.100 NaOH(aq) the student should add to 100 mL of 0.100...
