Lysergic Acid Diethylamide (LSD) was created by chemist Albert Hofmann in Switzerland while attempting to create a blood stimulant. The drug was utilized for psychological experiments for many years and this even led to the military experimenting with it as a biological weapon in the 1960’s. During the 1960’s‚ as a result to the wide dispensing of the drug for experimental purposes‚ it wound up being the “…counterculture used the drug to escape the problems of society…” (LSD: A Short History).

Abstract By using acid-base titration‚ we determined the suitability of phenolphthalein and methyl red as acid base indicators. We found that the equivalence point of the titration of hydrochloric acid with sodium hydroxide was not within the ph range of phenolphthalein’s color range. The titration of acetic acid with sodium hydroxide resulted in an equivalence point out of the range of methyl red. And the titration of ammonia with hydrochloric acid had an equivalence point that was also out of

Standardization of hydrochloric acid by sodium carbonate Concentrated hydrochloric acid is roughly 11 M. Pour out into a measuring cylinder about 2 cm3 of concentrated hydrochloric acid. Transfer it to a 250 cm3 flask and make up to the mark with water. Shake well. Put some pure sodium hydrogen carbonate or anhydrous sodium carbonate into an evaporating dish and heat gently over a low flame for about fifteen minutes‚ stirring continuously. Take care not to heat the mass too strongly or fusion
