Commercial Antacid Tablets Hydrochloric acid (HCl) is one of the substances found in gastric juices secreted by the lining of the stomach. HCl is needed by the enzyme pepsin to catalyze the digestion of proteins in the food we eat. Heartburn is a symptom that results when the stomach produces too much acid (hyperacidity). Antacids are bases used to neutralize the acid that causes heartburn. Despite the many commercial brand‚ almost all antacids act on excess stomach acid by neutralizing it with

STANDARDIATION OF ACID AND BASE Eunice Ivy B. Gamboa ABSTRACT Solutions of known concentration are prepared by dissolving measured masses of standard acids in distilled water. The concentrations of unknown solutions of sodium hydroxide are determined by titration. An acid solution reacts with a base solution in a "neutralization" reaction. Titrations permit the concentrations of unknown acids/bases to be determined with a high degree of accuracy. In order to analyze unknown acids/bases‚ we must have

COMMERCIAL (CENOVIS) TABLET ABSTRACT In this experiment‚ the vitamin C content of a commercial tablet is determined and compared with the manufacturers’ specification. Vitamin C is water-soluble and is an enantiomer of ascorbic acid. (Commercial vitamin C is often a mixture of ascorbic acid and other ascorbates.) Ascorbic acid‚ C6H8O6‚ is a reducing agent that reacts rapidly with iodine (I2). As the iodine is added during the titration‚ the ascorbic acid is oxidized to dehydroascorbic acid‚ while the iodine

phones? Nowadays‚ many people have smart phones and laptops. However‚ we now also have access to tablets. So now we will compare two of the newest most commonly used tablets. One is the new iPad‚ manufactures by Apple‚ and the other is the Galaxy tablet note 10.1‚ by Samsung. The tablets are quite expensive‚ the iPad is however priced at $629 and the galaxy note is $499. Both are high-resolution tablets. One can get normal usage out of the two if the batteries are fully charged. The main difference
