Question

1. Calculate the pH of a solution that is 1.00 M HF, 1.00 M HCl, and 1.439 MNaF. (K_a= 7.2 x10^–4)

I am getting 2.48 for this one

2. Calculate the pH of a solution that is 1.00 MHF, 2.00 M HCl, and 1.439 MNaF. (K_a= 7.2 x10^–4)

and for the second one i keep getting 2.48 or 0.25. Which one is it??
