Considering that a buffered solution may contain a weak acid and its salt or a weak base and its salt, the following combinations can not produce a buffer: - HOCl and NaCl because the salt should be NaClO (sodium hypochlorite). 21. HF and NaF. Reply. I ... 0.10M HClO4 and 0.10M NaClO4 II ... 0.075M H3PO4 and 0.075M KH2PO4 III ... 0.10M HCN and 0.050M KOH IV ... 0.050M KOH and 0.10M NH3 V ... 0.050M HNO3 and 0.10M NaF The correct answer is numbers II, III, and V - however, I do not understand why these are buffer … 0.35 M NH4Br and 0.37 M NH3 c. 0.12 M HCN and 0.21 M HCl d. 0.11 M KOH and 0.29 M KCl e. 0.36 M HNO3 and 0.29 M KNO3 5 Buffer Calculations 20. Chemical reaction. NH4Cl and NaOH NaOH + HClO4 --> NaClO4 … Find an answer to your question Which of the following combinations cannot produce a buffer solution?A) HNO2 and NaNO2B) HCN and NaCNC) HClO4 and NaClO4 D) NH3 … Tulsirani100 Tulsirani100 01.06.2019 - NH4Cl and NaOH because the base should be NH4OH (ammonium hydroxide) or the salt NaCl (sodium chloride). Which of the following aqueous mixtures would make a good buffer system? HClO4 and NaClO4. Select all that apply. Calculate the pH of a solution that is 0.30 M in ammonia (NH 3) and 0.20 M in ammonium chloride (NH 4Cl, K a = 5.62 × 10 –10). Since this is a buffer solution you need to add alot of base to this solution to raise its pH. HCN and LiCN. Sep 12, 2011 431 34 Status. Which among the buffer solutions is best fitted for the said purpose?justify your answer. 100mL 0.2M NaOH + 100mL 0.1M HClO4 I thought buffers could only be formed with a weak acid and its conjugate base or a weak base and its conjugate acid...? HCl which is Hydrochloric acid is a strong acid. a. This is different than HClO because of the oxygen atom. HOCl and NaCl. In protein precipitation, two liters of 5mM buffer solution with pH 5.2 is needed in the isolation of albumin. HClO4 and NaClO4 F. ... Isnt it a buffer as long as it consists of a weak . Calculate the pH of a solution containing 0.40 mol fluoride anion and 0.30 mol of hydrogen fluoride (HF). H2SO4 and Na2SO4. chemistry. 7+ Year Member. HNO2 and KNO2.
