The value of Kc for the reaction of hydrofloric acid in water to make the aqueous hydronium ion and aqueous fluoride ion is 0.00001577. The concentration of HF(aq) is 1.4307 M with no products. What is the equilibrium concentration (in M) of the hydronium ion? I understand the set up, I mostly need help with the algebra portion in getting the concentration.
CaF2(s)⇄Ca2+(aq)+2F−(aq) Ksp=3.9×10−11 HF(aq)⇄H+(aq)+F−(aq) Kc=6.8×10−4 The dissolution of calcium fluoride is represented by the equilibrium system above at 25°C.
