Homework Help: Calculating activity coefficients

  1. Feb 25, 2012 #1
    The measured pH of 0.100 M HCl at 25°C is 1.092. From this information, calculate the activity coefficient of H+.

    I tried using the Debye-Huckel equation and got 0.825 but it's not right. I don't know how else to solve for the activity coefficient.

    You are not asked to calculate theoretical value, but to calculate experimental value.

    What is pH that you have just measured? How does it depend on the concentration?
