The Most Potent Antacid
Science Fair Project made by: Nabiha Choudhury
Problem
Hypothesis
Material
- Grape Juice (no sugar)
- Eye Dropper
- Lemon Juice
- Several Test Tubes (I used glasses)
- Several different types of Liquid Antacids: Pepto-Bismol, Up&Up Liquid Antacid, Equate maximum strength Liquid Antacids, Gaviscon Extra Strength Liquid Antacid, Rolaids Liquid Antacid
Variables
Dependent variable-the change in color
Control variable- the amount of lemon and grape juice needed.
Procedures
- Add ten drops of grape juice to each test tube.Grape juice is a natural acid-base indicator ,so it turns colors depending on whether the solution it is placed in is a acidic or basic.
- Rinse the eyedropper thoroughly
- Add ten drops of lemon juice (an acid)to each test tube.
- Name each test tube with the name of one of the liquid antacids you are testing.
- Add the first antacid drop byr drop to the first test tube, stop as soon as it changes color.A color change means the antacid neutralized the acid in the lemon juice.
- Record the number of drops it took to make the color changes
- Repeat the process with the remaining types of antacid adding drops of one antacid to each remaining test tube.
- Record results.
Trial 1
Gaviscon-6 drops,Turned pink
Rolaids-5 drops,Turned black
Up&Up-16 drops,Turned hot pink
Equate-27 drops,Turned light pink
Trial 2
Gaviscon-7 drops,Turned pink
Rolaids-4 drops,Turned black
Up&Up-19 drops,Turned pink
Equate-22 drops,Turned light pink
Trial 3
Gaviscon-7 drops,Turned light pink
Rolaids-6 drops,Turned brown
Up&Up-15 drops,Turned dark hot pink
Equate-20 drops,Turned bubble gum pink
Results
3rd trial:10 drops,Turned light magenta
Gaviscon- 1st trial:6 drops,Turned pink,2nd trial :7 drops,Turned pink,3rd trial:7 drops,Turned light pink
Rolaids-1st trial:5 drops,Turned black,2nd trial:4 drops,Turned black,3rd trial:6 drops,Turned brown
Up&Up-1st trial:16 drops,Turned hot pink,2nd trial:19 drops,Turned pink,3rd trial:15 drops,Turned dark hot pink
Equate-1st trial:27 drops,Turned light pink,2nd trial:22 drops,Turned light pink,3rd trial:20 drops,Turned bubble gum pink
Conlclusion
Research
- Antacid works by neutralizing a acid in a chemical reaction
- It is used to relieve upset stomach,sour stomach, and heartburns
- Antacids have a rapid onset and short duration of action.Rapid relief
- Antacid might be in to classes.One that works with chemicals neutralization of gastric acid and one that uses adsorption of acid.(non-absorbable antacid)
- Chemical antacid show most rapid action,may cause a condition where the gastric acid relieves greater concentrations after drug effect stay
- Calcium and magnesium salts is adsorption of the acid,are less prone with the rebound effect
- An acid is a chemical substance whose solution characterized by a sour taste, and can turn blue litmus red
