Introduction: The purpose of this experiment was to help the student practice and familiarize themselves with antacids and with other forms of acids/bases. It also allowed the students an opportunity to actively raise and lower pH using the provided chemicals and to observe the effects of adding these chemicals with a pH indicator. The student was also able to determine the neutralization capacity of the antacids and use an indicator to determine the end-point of a reaction. Upon completion of this experiment all of these are achieved. Materials: Bogen’s Universal Indicator, Alka-Seltzer, Milk of Magnesia (4 oz.) Tums (1 roll), 1 M Sodium Hydroxide solution (20 mL), Syringe (5 mL), Acetic acid (vinegar), Balance, Large plastic cup, Small medicine cup, Graduated Cylinder (50mL) Tap water (room temperature), Sheet of white paper, Camera Method: This experiment had three main sections. To begin section one, gather all needed materials. Next carefully weight out 5g of Acetic Acid in your plastic cup. Once that is complete measure out 20mL of room temp. water with the graduated cylinder and pour it into your Acetic Acid while swirling to mix. Then add 5 drops of indicator and swirl to mix. Observe the color of the solution at this stage. Next
