Therefore‚ the experiment was performed to conduct quality control analysis on two commercial products to determine the amount of acid or base active in these two products and then compare the results to those of the manufacture. This was done through the preparation of standardized acid solution and standardized base solution‚ and through titration. The purpose of titration was to determine the concentration levels of the commercial products being used.

ChE 171 Assignment 1. Essential and Non-essential Amino acids Amino acids are organic compounds which contain both an amino group and a carboxyl group and may be divided into two groups basing on whether they are produced internally by the human body or not: essential and non-essential amino acids (hyperphysics.phy-astr.gsu.edu‚ 2012). An essential amino acid (indispensable amino acid) is an amino acid which an organism needs to ingest because it is necessary for
