Homework Help: K-value missing in acid-base problem?

  1. Mar 16, 2014 #1
    What initial concentration of HF (aq) in water would give a solution with a pH = 1.5?

    I think the K value is missing... How could we solve this problem?

    Hey there!
    I'm sure you know the K of water - what you're looking for is the Ka value of HF. Have you not been given the value?

    Is there a table of Ka values in your book?
