We will determine which product has the greatest acid neutralizing power per unit of cost. The active ingredient in an antacid is a base. A base is the opposite of an acid. When brought into contact with an acid both lose their characteristic properties, i.e. they are neutralized. The common bases used in antactid tablets are aluminum hydroxide (Al(OH) 3 ), magnesium hydroxide (Mg(OH) 2 , calcium hydroxide (Ca(OH) 2 or some combination of these. Although each will neutralize stomach acid, excessive use is not recommended. Aluminum hydroxide can cause constipation, magnesium hydroxide also functions as a laxative, and calcium hydroxide can stimulate extra acid production in the stomach to replace that which has been neutralized. Each of these antacids contains a chemical which reacts with the acid in your stomach, neutralizing it and reducing the excess acidity. We will add acid to the material of these preparations, and by measuring the amount of acid which is neutralized by the prescribed dosage, compare their capacities for acid neutralization. The chemical technique of neutralizing a chemical with a measured quantity of another chemical is known as titration. Your instructor will explain the concepts of titration, pH and indicators and will demonstrate the techniques involved. Then, you can carry out the procedures for the antacid preparation assigned to your group. We will compare results after you have finished. Take care to carry out your measurements with precision.

while constantly stirring to mix the contents. Close the stopcock periodically and swirl the flask. As you approach the end point, (the point at which all of the acid has been neutralized) each drop of acid will turn the solution purple, but after swirling it will return to green. At this point, add acid only one drop at a time. Continue to add acid, drop by drop, swirling the flask after each drop is added. When the purple color persists for one minute after swirling and an additional drop causes no deepening of the color, you have reached the end point. That is, all the antacid chemical has been used up, and the last drop of acid made the contents of the flask permanently acid. Record the final level of acid in the buret. final level_______________mL (3)

  1. Complete the Calculations and Question worksheet Now move to the Computer Lab  Each person in the group will have a different assignment o Assignment #1 : Using Inspiration, develop a concept map of the lab. Use your imagination. The pics from the camera can be used. o Assignment #2 and #3 : Using Publisher, develop a flyer to advertise which antacid is the best. o Assignment #4: Using Excel, graph the results from the Plop Table. Include Appropriate graphics.
