Pillbug Reaction In the Presence of an Acid Abstract: This experiment was conducted to learn how regular behavior of a pillbug is affected in the presence of a substance such as hydrochloric acid. Behavior of the pill bugs was first monitored and recorded to discern how the species acts under normal conditions. The behavior was then observed and documented after the pill bugs were placed in a choice chamber with HCl and water. There was no change in activity after these substances were placed

activation 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. Keywords: Activated carbon‚ Adsorption‚ Hydrochloric acid‚ Phosphoric acid‚ Zinc chloride I. Introduction

Use your answer to question 1 and the results in Table 2 to explain how mixing an alcohol of unknown structure with Lucas. Reagent can help one to determine whether it is primary‚ secondary or tertiary. Q5. Write down an equation for the reaction of tertiary butyl alcohol with concentrated hydrochloric acid

depending on the number of alkyl substituents directly attached to the carbon bearing the halogen atom. The purpose of this laboratory experiment was to prepare t-butyl-chloride‚ an alkyl halide‚ by dissolving t-butyl alcohol in concentrated hydrochloric acid. The reaction occurs via nucleophilic substitution‚ in which a nucleophile replaces the leaving group in the substrate. In this case‚ the hydroxyl group of t-butyl alcohol is replaced by a chlorine atom. The reaction proceeds via Sn1mechanism
