Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid‚ potassium acid phtalate (HKC8H4O4‚ abbreviated KHP). This will be accomplished using the titration

experiment teaches the students how to determine density‚ volume‚ and percentage errors. OBJECTIVE The objective of this experiment is to determine the order with respect to permanganate ion and to oxalic acid concentration for the reaction of potassium permanganate and oxalic acid solutions. Other goals include‚ writing a rate equation and determining the effect of increased temperature on the rate of this reaction. MATERIALS AND EQUIPMENT The materials required for this experiment include

What is LSD? LSD (lysergic acid diethylamide) is a synthetic (man-made) drug that has been abused for its hallucinogenic properties since the 1960s. If consumed in a sufficiently large dose‚ LSD produces delusions and visual hallucinations that distort the user’s sense of time and identity. LSD typically is sold as a liquid or applied to blotter paper‚ sugar cubes‚ gelatin squares‚ and tablets. LSD generally is taken by mouth. The drug is colorless and odorless but has a slightly bitter taste.

reagents such as Hydrochloric acid‚ Zinc Chloride and Phosphoric Acid were used. A single burn and double burn process was carried out for each method. The activated carbon obtained was compared in terms of absorption capacity‚ bulk density‚ BET specific surface area and pore volume. The best results were yielded for activated carbon prepared using phosphoric acid with the single burn technique.
