WebMar 28, 2024 · If you take x to be the equilibrium concentration of the hydronium cations, you can say that ["H"_3"O"^(+)] = ["F"^(-) ] =x "M " -> the two ions are produced in a 1:1 mole ratio ["HF"] = ["HF"]_0 - x -> the concentration of the acid decreases by x "M" In your case ["HF"]_0 = "0.05 M" and so the equilibrium concentration of the acid, i.e. what ...
WebAs we would expect for a weak acid, the percent dissociation is quite small. However, for some weak acids, the percent dissociation can be higher—upwards of 10% or more. For example, with a problem involving the percent dissociation of a 0.100 M chloroacetic acid, we cannot assume x is small, and therefore use an ICE table to solve the problem.
