Question 1

The equilibrium constant for the reaction A- + H+⇌ HA is:

◦ Ka.
◦ Kb.
◦ .
◦ .
◦ KwKa.​

Question 2

The equilibrium constants (Ka) for HCN and HF in H2O at 25°C are 6.2 × 10–10 and 7.2 10–4, respectively. The relative order of base strengths is:

◦ F–> H2O > CN–.
◦ H2O > F–> CN–.
◦ CN–> F–> H2O.
◦ F–> CN–> H2O.
◦ None of these.are correct.
