PH of a solution containing a strong acid and a weak acid

  • #1

Homework Statement


Find the pH in 50.0 mL of 1.00M HCl + 50.0 mL of 1.00M HF

Homework Equations


None to speak of really...

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.

Are you given the Ka for HF? If so, you can assume complete dissociation of HCl and use the given data to find the degree to which HF dissociates. Thus you can find the total no. of moles of H+ in the solution.
