when acetic acid reacts with a strong base like sodium hydroxide (NaOH)‚ the hydroxide ion from the base reacts with the hydrogen ion from the acid to produce water. The remaining sodium ion (Na+) and the polyatomic (CH3COO-) acetate ion form the soluble salt sodium acetate‚ NaCH3COO(aq)‚ which remains dissociated in solution. This acid-base reaction is called a neutralization reaction and has the general form: Acid + base a salt + water For the reaction of acetic acid with sodium hydroxide

Nitration and Purification of Bromobenzene Abstract: An electrophilic aromatic substitution reaction was performed on bromobenzene with nitric acid producing both 2-bromonitrobenzene and 4-bromonitrobenzene. Products of the reaction were purified through multiple recrystallizations and column chromatography creating multiple crops of a yellow powder. The percent yield of products was determined to be 51%. The melting point of Crop 1 was found to be 110-115 °C‚ and Crop 2 was found to be 37-90

discarded and each pellet was resuspended in 150ul of TE buffer(10mM Tris-HCl‚ pH 8.0; 0.1 EDTA). 300ul of SDS(1% SDS‚ 0.2 N NaOH) was added to each pellet. The tubes were placed on ice for five minutes‚ after which‚ 225ul of ice-cold 3M potassium acetate(pH 4.8) was added. The tubes were again placed on ice for five minutes and subsequently microfuged for five minutes. The supernatants were recovered and transferred to new tubes. One volume of phenol/chloroform was added to each new tube.

The New Look In February 1947‚ Christian Dior introduced the first major postwar collection‚ called the "Corolle Line"‚ which was later renamed the "New Look" by American journalists in Life Magazine (Fashions of the 1950 ’s: The "New Look). Dior was over the harsh utility style clothes and their masculine characteristic. With the "New Look"‚ most recognizable by its curvy shape and line‚ Dior started the fashion revolution away from the wartime mode (Fashions of the 1950 ’s: The "New Look)

Chapter 1 Summary In chapter one it talks about how hemachromatosis is a hereditary disease and it’s the most common genetic disease for people of European descent‚ in which the body can’t register that it has enough iron. So it keeps absorbing as much of it as possible‚ and this can have very‚ serious side effects (including death). Iron is very important for bacteria‚ cancer‚ and other things to grow. The way this disease is most easily treated is blood letting. Looks like all those crazy blood-letting
