If a solution of HF (Ka=6.8×10^−4) has a pH of 3.50, calculate the concentration of hydrofluoric acid.
So far, I've made 5 incorrect attempts at the answer and have one attempt remaining. My answers were as follows:
0.00015, 1.5x10^-4, 1.5x10^-5, 0.001, and 0.00032 (This last answer prompted the website to tell me: "This value is the concentration of H+. This concentration and the Ka value can be used along with the equation for Ka to determine the initial concentration of hydrofluoric acid. Ka=[H+][F−] / [HF]").
