Can somebody explain how do you write a Mass Balance or Charge balance for a acid-base equilibrium? Let say, if you are given 0.01M Zn(OH)2 in a saturated NaOH solution and also given that Zn(OH)2 + 2OH- -> Zn(OH)4(2-) how would you solve the mass balance/charge balance? I really have no idea...
1. Homework Statement
Given the following half-reactions:
Ce4+ + e− → Ce3+ E° = 1.72 V
Fe3+ + e− → Fe2+ E° = 0.771 V
A solution is prepared by mixing 7.0 mL of 0.30 M Fe2+ with 8.0 mL of 0.12 M Ce4+.
Calculate [Ce4+] in the solution.
I've got the potential of a platinum electrode...

please help! questions on pKa of Phenol
Hi, I have some questions regarding the pKa of Phenol lab that I am working on right now.
1) What would cause the absorbance curves to not go through the isosbestic point?
For this one, I know that isosbestic point is not pH dependent so pH won't...
