Hi all this is an easy and perfect way to calculate percentage of ionization.

remove consider this is nothing at the time of reading this formula because i tried to put the space but i could not so i put that word

(consider this is nothing) 100
% of Ionization = -----------------------------
(consider this is nothing, this is space) ChargeX(pH-pKa)
(consider this is nothing, space) (1+10)

if pH < 7 charge is (-)
if pH > 7 charge is (+)

formula to calculate percentage of Ionization is [100]/{(1+10)rest to charge multiplied by pH-pKa}

one more thing to find out percentage of ionization is rule of Nine you can find this in CPR, Leon Shargel, Chapter - 12, page 239
look for percentage Ionization

I hope this help

if you need any help let me know

thanks and best of luck to u all

thanks for this i have a question that i couldnt solve can u try
a solution contain methylacetat (0.1)M and sodium hydroxide (0.1) M if the rate constant for this reaction is 1.082 liter(mole/min) at temprature 25 c0 how mant min will it take for the concentration of methylacetat to fall to 0.09 M?
