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
