Based on the chemical structure, which of the following solutions would have the highest pH? Hint: Assume equimolar concentrations for all solutions. Weakest acid or strongest base would have the highest solution pH.

Which of the following could NOT act as a Lewis acid?

What is the percent ionization in a 0.600 M solution of hydrofluoric acid (HF)? Note: The Ka of hydrofluoric acid, HF, is 6.8 × 10⁻⁴.

Which of the following aqueous solutions has the lowest ?  Hint: This is not a calculation problem. Consider the type of acid/ base (strong vs. weak acid and base).

What is the Kb value for the conjugate base of HCN (Ka = 4.9 × 10⁻10)? Hint: All Ka/Kb values are at 25°C.

Which of the following can act as a Lewis acid?

What is the percent ionization in a 0.400 M solution of hydrofluoric acid (HF)? Note: The Ka of hydrofluoric acid, HF, is 6.8 × 10⁻⁴.

At 25°C, the pH of a solution is 8.43.  Which of the following statement is FALSE about this solution?
