A-Level Chemistry Coursework Investigation:- Finding the Empirical Formula Of Aluminium Chloride By Yasir Al-Wakeel Introduction: The purpose of this experiment is to find the empirical formula of a sample of anhydrous aluminium chloride by titrimetric analysis. The empirical formula of a compound, as opposed to the molecular compound, is the simplest formula which represents its composition. This shows the elements present and the ratio of these elements. The molecular formula, on the other hand, is a simple multiple of the empirical formula and shows the actual number of atoms of the different elements in one molecule of the compound. Thus ethene, a homologue of the alkenes, has a molecular formula of C2H4 , whilst the empirical formula of ethene is CH2. To find an empirical formula the ratio of the amounts (in moles) of the elements is required, which in this particular experiment is to be found by means of titration. ...
