can someone please tell me if this is correct? i dont feel right about it and dont quite understand 
Which of the following solution pairs can be used as buffers? (Check all that apply) □HOH/KOH HNO3/KNO3 NH4CI/NH3 K2CO3/NaHCO3 Na2CO3/K2CO3 Question 9 Explain why you chose each answer in the problem above. Edit View Insert Format Tools Table 12pt Paragraph BIUA 2 T² E 1. No, because KOH is a strong base and HOH (H₂O) would be its solvent. 2. No, because HNO3 is a strong acid and KNO, is a salt of a strong acid (HNO3) and a strong base (KOH). 3. Yes, because NHgis a weak base and NH CI is the salt of a weak base NH, and a strong acid HCI. 4. No, because K₂CO, is a weak base but NaHCO, is not its conjugate base. 5. No. because K₂CO3 is a weak base and Na CO₂ is the salt of a strong base and a weak acid MacBook Air
