Synopsis The purpose of this experiment was for students to prepare some simple organic compound and to purify the compound by recrystallisation. This experiment allowed the students to conduct the synthesis of aspirin‚ acquire the skills of recrystallisation using normal filtration and reinforce the technique of the melting point determination. The method used to synthesize aspirin was esterification by reacting salicylic acid with acetic anhydride with the presence of dehydrating agent‚ conc

INORGANIC CHEMISTRY – CLASS XI (ISC) Properties of Group 1 elements [Alkali metals] 1. Due to high reactivity‚ alkali metals do not occur free in nature. Elements of group 1 (or IA) are known as alkali metals because their hydroxides are soluble in water and form strongly alkaline solutions. Alkali metals are stored under kerosene oil because they get tarnished on exposure to air. 2. The general electron configuration of alkali metals is ns1. 3. Alkali metals have largest size and lowest

Discuss how primary research and evidence based practice (EBP) differ and how they complement each other. Primacy research and evidence-based practice (EBP) differ in that primary research or nursing research is what engenders EBP therefore you must have the research to produce the EBP. Primary nursing research is disciplined analysis constructed to produce evidence regarding nursing issues such as education‚ clinical practice guidelines‚ informatics and nursing administration.
