1. The problem statement, all variables and given/known data Find the pH in 50.0 mL of 1.00M HCl + 50.0 mL of 1.00M HF 2. Relevant equations None to speak of really... 3. The attempt at a solution I figured out [HCl] and [HF] in the solution: they're both 0.5M. I have absolutely no idea what to do at this point... Thanks.
