Titrations: Analysis of Antacid Tablets Cuenca‚ Carlo Nicolo B. Del Prado‚ Rockson D. MEB21 Bachelor of Science in Biology – Major in Medical Biology College of Science De La Salle University – Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT This experiment was performed to learn the technique of acid-base titration and to compare the efficiency of commercially available antacids by looking at their weight of HCl and weight of antacid values. The analysis of antacid tablets was highlighted

indicator in this way and it works well also. ***Antacid tablets will only neutralize the acid very slightly ( maybe it will bring the pH up from 1 to 1.2). You will not observe a color change in your indicator. The baking soda will neutralize more acid and will bring about a color change. This could stimulate a discussion about the effectiveness of antacids versus baking soda as a treatment for acid indigestion. It turns out that the antacids are best because you would not want to completely

EXPERIMENT SIX - ANALYSIS OF STOMACH ANTACID TABLETS Purpose In this experiment you will measure the amount of stomach acid consumed (or neutralized) by various antacid tablets (Maalox‚ Tums‚ Rolaids: no Pepcid or Tagamet!). If you have a favorite one‚ bring a package to the lab (one color only). Inside your stomach‚ excess hydrochloric acid is neutralized by the antacid. Different antacids use different metal hydroxides‚ such as Al(OH)3 or Mg(OH)2. The general formula for this reaction

Green Chris Christopher is in his last year of his degree in Agrobiology. He needs to complete a 6 months internship with the Agri-food and Veterinary Authority AVA of Singapore. He has prior experience in growing crops of tomato and achieving at least a 95% yield. In the lab‚ his supervisor Dr Ong decided to challenge him. Dr Ong said: “Hi Christopher‚ welcome to our AVA laboratory. We are pleased to have you here. We have some problems growing Rhododendron.” Christopher replied: “Thank you

Relief will happen usually in just a few minutes. Neutralization is a chemical reaction (also called a water forming reaction since a water molecule is formed during the process) in which an acid and a base or alkali (soluble base) react to produce salt and water (H2O). During the process‚ hydrogen ions H+

An acid is a substance with particular chemical properties including turning litmus paper red‚ neutralizing alkalis‚ and dissolving some metals. It can be corrosive or it can be sour liquid of this kind. Acids are also all around us in everyday life‚ for example‚ carbon dioxide gas dissolves in rain to form carbonic acid (a weak acid). We find acids in many foods‚ such as ethanoic acid in vinegar. These acids are not hazardous. Some acids‚ which are found in the laboratory a car battery are too dangerous

LAB 6. ACIDS AND BASES: PH AND BUFFERS PURPOSE: To determine the pH of common acids and bases using a pH meter‚ pH paper‚ and red cabbage indicator. To test the effect of adding an acid or base to a buffer solution. SAFETY CONCERNS: Always wear safety goggles. Wash with soap and water if skin contacts acids or bases. ACIDS: An Acid is a substance that when dissolved in water will produce hydrogen ions‚ H+‚ in the solution. An acid that does not contain carbon is called an inorganic
