Ionisation formula

WebWe also need to calculate the percent ionization. So the equation 4% ionization is equal to the equilibrium concentration of hydronium ions, divided by the initial concentration of the acid, times 100%. The equilibrium concentration of hydronium ions is equal to 1.9 times 10 to negative third Molar. So we plug that in.
