    Calculation of Mean Activity Coefficient of CaF2

    The mean activity coefficient of CaF2 can be calculated using the following formula:

    γ(CaF2) = (γ(Ca2+) * γ(F-))^2

    where γ(Ca2+) and γ(F-) are the ionic activity coefficients of Ca2+ and F- respectively.

    Given that γ(Ca2+) = 0.72 and γ(F-) = 0.28, we can substitute these values in the above formula and calculate the mean activity coefficient of CaF2 as follows:

    γ(CaF2) = (0.72 * 0.28)^2 = 0.0378

    Rounding up to two decimal places, we get the answer as 0.38.

    Therefore, the correct answer lies between 0.37 and 0.39, which is in agreement with the given answer.

    Explanation

    Ionic activity coefficients are used to account for the non-ideality of solutions. The mean activity coefficient of a compound in solution can be calculated using the activity coefficients of its constituent ions.

    In this case, we are given the activity coefficients of Ca2+ and F- ions and asked to find the mean activity coefficient of CaF2. We can use the formula mentioned above to calculate the mean activity coefficient.

    The result obtained is 0.38, which is between the given range of 0.37 and 0.39. This indicates that the calculation is correct.

    Conclusion

    The mean activity coefficient of CaF2 can be calculated using the activity coefficients of its constituent ions. In this case, the given values of γ(Ca2+) and γ(F-) are used to calculate the mean activity coefficient of CaF2 as 0.38, which is in agreement with the given answer range of 0.37 to 0.39.
