Answer:

pH = 2.88

Explanation:

For a weak acid solution, the pH can be calculated using the following formulas:

  • [H⁺] = [tex]\sqrt{Ka*C}[/tex]
  • pH = -log[H⁺]

Where Ka = [tex]10^{-pKa}[/tex] and C is the molar concentration.

We are given Ka and C by the problem, meaning we can now proceed to calculate [H⁺]:

  • [H⁺] = [tex]\sqrt{1.7*10^{-4}*0.01}[/tex]
  • [H⁺] = 0.0013 M

Finally we calculate the pH:

  • pH = - log (0.0013) = 2.88
