Calculate the pKa of hydrofluoric acid (HF(aq)) and hydrogen cyanide (HCN). What would be the pH of a solution containing 5 mM HF? What would be the pH of a solution containing 5 mM HCN?You do not need concentrations. Standard Gribbs Free energy for HF is -296.8 and for HCN is 124.7 This calculation assumes the acid is completely dissociated. You need the pKa to figure out how much of the H+ is free. This was all I was given. I do not know where to start, what I need, or what I need to calculate first. There are no other instructions or parts to this question. I'm at a loss, where do I begin?
