antacid tablet experiment

Equipment for illustrating the use of indigestion tablets to neutralise hydrochloric acid. Crush a tablet using a pestle and mortar and carefully transfer it to a conical flask, using a spatula to ensure complete transfer as far as possible. Rinse any remaining fragments into the flask with a few cm 3 of deionised water.

of these molarities for analyzing the antacid in the next part of the experiment. Back-titration of an antacid Choose a brand and obtain 2 antacid tablets. Avoid touching them with your fingers as much as possible. Record the brand name, cost per package and number of tablets per package. Weigh each tablet separately on weighing paper to the ...

1. Your instructor will assign you an antacid to investigate. 2. Record the name and the names and amounts of the active ingredients each tablet. This information is on the label of the antacid bottle. 3. Measure and record the mass of a single tablet of your assigned antacid. 4. Record the concentration of the NaOH solution being used. 5.

Take the fourth tablet and ground it into a powder. To do this, put the tablet to be ground inside a clean, folded piece of paper. Place the folded paper on a solid surface and use a spoon to ...

Alka-Seltzer is a medical drug that works as a pain reliever and an antacid (antacids help neutralize stomach acidity, such as heartburn). The pain reliever used is aspirin and the antacid used is baking soda (sodium bicarbonate, NaHCO 3).To take the tablets, they should be fully dissolved in a glass of water.

The purpose of this investigation was to determine the most effective brand of antacid medication that best neutralises stomach pH at the 5-minute time period. In this experiment, four different brands of antacid tablets (Eno, Rennie, Mylanta and Gaviscon) were tested for their effectiveness of neutralising hydrochloric acid (pH 0.9, 160mM).

Antacids are bases that react stoichiometrically with acid. The number of moles of acid that can be neutralized by a single tablet of a commercial antacid will be determined by back titration. To do the experiment, an antacid tablet will be dissolved in a known excess amount of acid. The resulting solution will be acidic because the tablet did ...

analyzing the aspirin tablet in Lab 2. For today's experiment, you will first determine and record the weight of an antacid tablet. Then the tablet is crushed (to speed up the reaction), and the entire amount is placed into a weigh boat or onto a piece of weighing paper, and weighedagain. (It is common to lose some the tablet during the ...

In this experiment, several brands of antacid tablets will be compared for their capacity to neutralize hydrochloric acid. 7A Experiment In this experiment, you will add an antacid tablet to a known quantity of 0.50 M HCl that exceeds the amount required for reaction with the tablet. Standardized NaOH solution will be

Antacids have been developed to treat short-term excesses. Other pharmaceuticals are used to treat long-term imbalance of acid production. Students may be surprised how little the pH changes when the antacid is added. It is interesting to compare liquids with powders, and to see just how slowly an uncrushed tablet reacts.

Antacids: An Inquiry Study. Students use a pH sensor to investigate how antacid tablets work and use a back titration method to determine how much of the active ingredient is found in one tablet. Supports NGSS Performance Expectation HS-PS1-7: Use mathematical representations to support the claim that atoms, and therefore mass, are conserved ...

Experiment setup. Crush one indigestion tablet using the pestle and mortar. Add 50 cm 3 of distilled water and mix. Measure the pH using the pH probe, start recording the pH after about 1 minute (when the pH is relatively stable). After about 50 seconds add 1 ml of dilute hydrochloric acid. Monitor the change in pH.

Experiment 12 . Comparison of Antacid Tablet Effectiveness Overview. In this experiment, several brands of commercial antacid tablets were analyzed by students for their ability to neutralize stomach acid. Students were asked to write their findings on the chalkboard so that a comparison could be made as to the cost-effectiveness of the various ...

I. Introduction In this experiment, three brands of antacids (Tums, Equate, and Phillip's) were analyzed to determine their efficiency and cost-effectiveness. To analyze an antacid's ability to neutralize acid, the crushed antacid tablet dissolves in an excess amount of HCl with a known concentration.

Equation 1 says that when an acid and a base react together, they produce a salt and water. Stomach acid mostly contains hydrochloric acid (HCl), a very strong acid.The active ingredient in many antacids is calcium carbonate (CaCO₃), a base that is actually found in several natural minerals, including limestone, marble, and chalk.This acid and base react as shown in Equation 2 below.

These products, known more commonly as antacids, neutralize excess stomach acid by absorbing excess H+ ions. Antacids come in liquid form (Pepto Bismol, Milk of Magnesia, Maalox), effervescent form (Alka-Seltzer), and in tablet form (Rolaids, Tums, etc.). In this lab, you will test the effectiveness of different over-the-counter antacids by ...

Discussion: Experiment 8 (Antacid Analysis) The goal of this lab was to utilize acid-base back titration in order to neutralize antacid tablets. We did this by utilizing both HCl and NaOH and the way the two chemicals react. ... The percent of CaCO 3 in the antacid tablets is less than 100% because there is also a significant amount of Mg(OH) 2 ...

Antacid Experiment. Planning Experimental Procedures. Our aim of this experiment is to find out which antacid tablet works the best. In this project we were trying to find out how the speed at which an ordinary indigestion tablet will dissolve when it comes into contact with Hydrochloric Acid, which is more commonly found in the stomach.
