Can someone explain this problem step by step? Thank you
8) Preparation of buffer 4 4 Attempts Partially complete You have at your lab bench the following chemicals: NaH,PO,(s), Na2HPO4(s), Na PO,(), NH, CI(S), NaCH, COO(s), CH, COOH(1), 1.00 M NH , 1.00 M NaOH, 1.00 M HCl, and deionized water. You also have standard glassware available. Describe how you would make 500 mL of buffer with a pH of 5.00 using only one of the pure substances and one of the 1.00 M solutions (HCl or NaOH) so that the total concentration of the conjugate acid/base pair is 0.200 M (acid] + [base] = 0.200 M) a. Select the appropriate pure substance (solid or liquid) CH,COOH(1) b. What volume of the 1.00 M solution should be introduced in the flask? 100.04 mL c. What mass of the pure substance should be introduced in the flask? 2 g d. What is the pH after adding 10.0 mL of 1.00 M of the NaOH to the buffer solution? 2 report to at least 2 places after the decimal Evaluate Change Problem Values
