Ionization of ch3cooh
Webapproximation will not affect the calculated pH of a solution if the % ionization of the acid is less than 5%. We call this the 5% rule. In situations where the 5% rule does not apply, you’ll need to use the quadratic formula to solve for x in the ICE table: a b ac a b ax x 2 4 2 For equations of the form bx c 0, 2 2 + + = =− ± − http://butane.chem.uiuc.edu/anicely/chem102dfa10/Worksheets/Worksheet19_acidbase2_Key.pdf

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.
