Problem- You are titrating 150.0 mL of 0.070 M Ca2 with 0.070 M EDTA at pH 9.00. Log Kf for the Ca2 -EDTA complex is 10.65, and the fraction of free EDTA in the Y4 form, Y4â, is 0.041 at pH 9.00.
a) What is K\'f, the conditional formation constant, for Ca2 at pH 9.00?
b) What is the equivalence volume, Ve, in milliliters?
c) Calculate the concentration of Ca2 at V = 1/2 Ve
d) Calculate the concentration of Ca2 at V = Ve.
e) Calculate the concentration of Ca2 at V = 1.1 Ve.
I am need of complete solution for this problem please help- me out to get right solution
Calculate the concentration given the absorbance. Each test tube has 5ml of water then a certain amount of bromol blue. 1 ul bromol blue absorbs at= 0.092, 2 ul=0.105, 4ul=0.093, 10=0.199, 20= .225, 30= 0.592, 50=0.957, 100= 1.717.

Grignard reagents can be used as nucleophiles in other reactions such as SN2 reactions. What would be the product for the following SN2-like reaction of an epoxide?
Predicting the Polarizability of a Molecule. Consider the following set of data for polarizability. From what I have learned, the simplest model for predicting the polarizability of a molecule is to assume that polarizability scales with the type.
