Topic: Calculating pH of a weak base given pKb (Read 2450 times) Could anybody lend me a hand with this calculation:
A salt produced from a strong acid and a weak base yields a solution that is acidic. Summary Calculations to determine pH of salt solutions are described. Practice Work the problems at the link below: http://www.sparknotes.com/chemistry/acidsbases/phcalc/problems.html Review In the first exa...
[weak acid]=Ca-[H+]+(Kw/[H+])[salt]=Cs+[H+]-(Kw/[H+])And now buffer composition becomes easy to calculate if you know the pH you desire: activity-correct back to the required [H+], plug that in along with the Ka (given) and Kw (we're taking a constant at 1*10-14 ...
I recognise that you are saying that for a weak base (with only one insoluble salt BHCl) total solubility St at lower pH is given by the last of the first set of equations, but at higher pH by the corresponding one in the second set. There is a sharp transition between the ...
Leakage of the internal phase droplets reduces the extraction efficiency of emulsion liquid membrane systems by spilling the stripping agent and previously extracted solute into the bulk phase. When the stripping agent is acid or base, internal phase leakage can be determined from bulk phase pH ...

This equation relates the pH, the ionization constant of a weak acid, and the concentrations of the weak conjugate acid-base pair in a buffered solution. Scientists often use this expression, called the Henderson-Hasselbalch equation, to calculate the pH of buffer solutions. It is important to ...
pH effectsA general equation relating the observed retention factor to the pH of the mobile phase, the dissociation constants, and the retention factors of the different ionic species has been derived. This equation is applicable to polyprotic weak acid and base dissociation events, that is, the...
Calculating the pH of a solution «on: I'm very rusty with chemistry, and I understand the concept of a buffer, but I'm still stuck with this problem. The formal composition of an aqueous solution is 0.12M K2HPO4AND 0.08M KH2PO4. Calculate the concentration of all ionic and molecula...
