Titration of the excess unreacted EDTA required 15.9 mL of 0.0220 M Ca2 . The Cd2 was displaced from EDTA by the addition of an excess of CN-.
what is the purpose of the anhydrous cacl2? the important that none of the solid cacl2 be included in the final distillation of 1-bromobutane.
What is the concentration of the solution as a mass percentage?
dissolved in water to produce a 0.0172 M solution. The pH of the resulting solution is 2.34. Calculate the Ka for the acid.

What would be the charge of the imidazole side chain of histidine at pH 7? Assume the pKa of the side chain is 6.0. 8) Assume the pKa of the alpha-carboxyl group = 2.0 and the pKa of the alpha-amino group = 10.0. What would be the net charge of gly..
65.50 mL of 0.161 M HF is titrated with 0.1200 M NaOH. What is the pH at the equivalence point.
What specific properties are mentioned in the organization of the real periodic table? How do they relate to the current model (pages 192 - 193)?
Clearly indicate coordinate system used in finding the answer. Basically trying to work up to building the molecular orbital diagram. I am stuck in the step where you determine the transformation sequences of each symmetry subset.
