most simple bath bomb recipes have: baking soda‚ citric acid‚ and cornstarch. When baking soda and citric acid are mixed together with some water‚ they undergo a chemical reaction. Specifically‚ this reaction involves acid-base chemistry‚ since the baking soda—also known as sodium bicarbonate (NaHCO3)—is a weak base‚ and citric acid (C6H8O7) is a weak acid. This reaction is shown in Equation 1‚ below. As you can see from Equation 1‚ the acid-base reaction produces carbon dioxide (CO2) gas. This gas

generated by the pharmaceutical industry is a prime example of how important organic chemistry is to our healthcare industry. In this lab‚ you will perform an organic synthesis to make aspirin. Aspirin is the trade name for the molecule acetylsalcylic acid. The earliest known use of this molecule has been traced back to fifth century B.C. The Greek physician Hippocrates described an extract of willow tree bark‚ a bitter powder that could be used to reduce fevers. In 1829‚ salicin was isolated from willow

caused when someone’s stomach produced excess amounts of gastric acids. One of the abundant acids is Hydrochloric Acid (HCl); this acid has a pH level of 1. When there is too much acid in our stomach‚ it rises up to the esophagus‚ which causes the burning sensation known as heartburn. You can treat this if you take antacids‚ antacids are mild bases that can help neutralize the stomach and ends heartburn. GENERAL NEUTRALIZATION EQUATION: Acid + Base = H2O + NaCl HCl + NaOH = water + salt Purpose

Abstract Our study is entitled “The Feasibility of Aspartic Acid found in Oyster Shells as an additive ingredient in improving the absorbency of commercialized sanitary napkins.” The objective of the study was to extract a protein from the oyster shells to produce aspartic acid which can replace the manufactured polymer found in commercialized sanitary napkins. The significance of our study is that the product is an alternative in producing polymers. It is also environmental friendly; biodegradable

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
