Alka-Seltzer had the most drops of the acid‚ 0.1M HCl added to the antacids until it gave us a yellow color. This antacid had the most drops added was because when something becomes neutralized‚ this means that the sample is absorbing more hydrogen bonds and this is produced by the hydrochloric acid passed by the stomach. Based on these results‚ Alka-Seltzer would have to have a less dosage for the amount of antacid in a tablet since it neutralizes the most acid. For Rolaids and Tums to reach

1. Clean‚ rinse‚ and fill a buret with NaOH solution just as you did in last week’s experiment. Record the molarity of the NaOH and the initial NaOH volume reading from the buret (+0.02 mL). 2. Weigh an antacid table in a weighing boat and record the mass (+0.01 g). Transfer the tablet to a clean mortar and crush the tablet into a fine powder using the pestle. 3. Weigh about 0.2 grams (+0.01 g) of the ground up tablet powder and transfer it to a clean 250 mL Erlenmeyer flask. 4. Transfer

Chemistry Research Paper What is an anti acid? According to Cindy Quarters (2010)‚ “Antacids are medicines that are taken orally to help relieve sour stomach‚ heartburn‚ or acid indigestion”. This medicine is available without prescription but it is needed to take the correct dose. The different types of anti acids include calcium carbonate‚ sodium bicarbonate‚ magnesium hydroxide‚ aluminum hydroxide‚ and dihydroxyaluminum sodium carbonate. The cost of the anti acid will depend on how effective

Soda has many uses; it can be used in cooking as well as cleaning‚ as an antacid and can also be used to fight odors. Properties: Baking Soda is odorless and can be used as an antacid because of the Bicarbonate ion. Common Name: Antacids Scientific Name: mainly metal hydroxides Formula: MOH Fundamental particles: Antacids are comprised of one metal ion and one or more Hydroxide ions. Usage: Antacids are used to neutralize stomach acid. Properties: The hydroxide ions

standards and accurately reflect the experimentally determined content of CaCO3 in each tablet. Titralac antacid had a measured mass of 0.4031g and this was determined to be 96% accurate based on the labelled mass. Quick-eze antacid had reasonable quality control with a measured mass of 0. 7491g‚ this being 93.6% accurate based on the label. Tums displayed lower quality control as the antacid had a measured mass of 0.7491g‚ which was only 84.1% accurate compared to the labelled mass. Overall‚ tablet

pharmaceutical companies are looking towards the OTC market for revenue protection and lifecycle extension for their major products. Although certain sectors of the OTC market are maturing‚ growth opportunities do exist in emerging markets and the leading antacids such as Mylanta‚ Maalox and Tums‚ those products ’ market share dominance will be challenged. Currently‚ many firms sought to overcome their lack of experience in marketing consumer products through alliances of various forms—mergers‚ joint ventures
