Which of the following solutions would have the highest pH? Assume that they are all 0.10 M in acid at 25.C. The acid is followed by its ka value. HCIO₂, K₂ = 1.1 x 10-2 HC₂H302, K₂ = 1.8 × 10-5 HF, K₂ = 3.5 × 10-4 O HNO₂, K₂ = 4.6 x 10-4
We wish to make a buffer solution at a pH of 9.50. Which of the following acids and its conjugate base salt would be most helpful? O CH3COOH K₂= 1.8 x 10-5 OC C6H5COOH K₂= 6.14 x 10-5 CICH₂COOH K₂= 1.36 x 10.3. K₂= 1.6 x 10-10 OC₂H5OH
Which of the following mixtures would result in a buffered solution? Mixing 100.0 mL of 0.100 MHCI with 100.0 mL of 0.100 M NaOH. Mixing 100.0 mL of 0.100 M NH3 (Kb = 1.8 x 10-5) with 100.0 mL of 0.100 M म. NaOH. Mixing 100.0 mL of 0.100 MHCI with 100.0 mL of 0.100 M NH 3 K-1.8 x 10-5. Mixing 100.0 mL of 0.100 M NH4Cl with 100.0 mL of 0.100 MNH3 Kb = 1.8 x 10-5
