Solve these questions 2 and 3

B) Write the reaction that would take place if a strong acid (H30. ) were added to the system. Hgot + HQ - = HO+ H,S C) Write the reaction that would take place if a strong base (OH ) were added to the system. YOU DO: OH + H , S = H 20 + HS - 1) Write the equation for the buffer system containing formic acid, HCOOH, and sodium formate, NaHCOO. HCOOH, )+ HCOO ing - 2HCOO ing + H+ (ag) Write the net ionic equation for the reaction that would take place if HCI was added to the buffer. HCOO rags + H +(ag) - HCOOH cag) Write the net ionic equation for the reaction that would take place if KOH was added to the buffer. OH cag + HCOOH (ag) HCOOjag+ H20 (1) 2) Which of the following combinations of materials would result in a buffer solution? *100. ml of 1.0 M HCI + 50.0 mL of 1.0 NaCl *100. mL of 1.0 M HNO2 + 100. ml of 2.0 M NaNO2 *100. ml of 1.0 M CH3NH2 + 100. ml of 0.50 M CH3NH3+ *100. ml of 1.0 M HF + 50.0 ml of 1.0 M HCIO 3) Explain why adding a small amount of acid to a buffer doesn't change the pH but adding a large amount does change the PH. 2 TOPIC: 8.8 Properties of Buffers by Emily Miller is licensed under CC BY-NC-SA 4.0.
