Determine the concentration of the HCL solution from the data for the standardization of the HCl with the Na2CO3 Na2CO3 had 0.0826 grams in 25ml of water Initial volume of HCl in the burette was 50ml Volume of HCl in the burette at the end point was 39.6ml
Why is tetraphenylporphyrin (TPP) so stable? Why is it planar? Why does it precopitate so easily?
Determine the complete formula for hydrated nickel(II) sulfate and its proper name. (show all steps)
Draw both extended and Fischer representation of each of these compounds.
For our experiment we put 5 mL of red Kool-Aid in an empty 25 mL volumetric flask, we then slowly added water until it reached the 25 mL mark in the flask and recorded our observations. Obviously the red Kool-Aid was diluted by the water making it..
The crossed aldol condensation of acetaldehyde with benzaldehyde is aided by the fact that benzaldehyde bears no α-protons. However, a possible competitive reaction is the “selfcondensation†of two molecules of acetaldehyde.
