hey .. I dunt know how to express but i am extremely thankful to you...
Actually, I am using this in determining the ionic concentration of ionic species in fermentation media. therefore, I need to compute the different concentration at the set pH. Well, this is just the start ... and which why i started up computing the pH of the simple systems.
Secondly, I did quite figure how mathemetically you ended up getting the value of 4.44 and also was not quite sure how did u get 4.69 itself.. Could just gimme the hint like which equation u used for computing the pH without the activity coefficient(I) and with it. I will be extremely glad if you could help me in this situation.
Also didnt understand the derivation of the diprotic equation, like pH = Pk1 + Pk2. I have a firm believe that the phosphoric acid will not interfere my case . Thanks again to make me understand that acid do interfere in situation..I hope you will help me solve these two questions ..
You calculator is extremely help it made my life a a lot easy.. Thanks to trial version.
Thanks a lot
Ashmit
