UNKNOWN SAMPLE #97 COMPLEXOMETRIC DETERMINATION OF WATER HARDNESS DR. BUDRUK CHM 152 LL SEAN MARKIS 4 FEBRUARY 2015 Introduction Using a Lewis base neutral molecule to donate electron pairs (ligands) to a Lewis acid metal ion center to form a single cluster (complex) ion. When the complex ions forms with a metal ion (chelation) the ligand used is called the (chelating agent). EDTA acts as a great chelating agent due to the Nitrogen and Oxygen donating an electron pair to the

Maxima and Minima First Derivative Test 1) We are given the function First‚ we find the derivative: We set the derivative equal to 0 and solve: Since the domain of f is the same as the domain of f’‚ 4 is the only critical number of f. Testing: x < 4 | f’(0) = -8 | f is decreasing | x > 4 | f’(5) = 2 | f is increasing | By the First Derivative Test‚ x = 4 is a local minimum. 2) We are given the function First‚ we find the derivative: We set the derivative

Undoped and Ce doped ZnO thin films were prepared by the sol-gel process. Zinc acetate dehydrate was dissolved in a mixture of absolute ethanol and monoethanolamine (MEA) yielding to a precursor concentration of 0.4 M .The MEA to zinc acetate molar ratio was set to 1. For doped films‚ cerium nitrate was added to the mixture with an atomic percentage fixed at 0.1‚ 0.3‚ 0.5‚ 0.7‚ and 0.9 at.% Ce‚ respectively. The resulting sols were magnetically stirred at 60°C for 1 hour and then aged at room temperature
