Transcript of antacid potency

research about antacids
Antacid, any one of several basic substances that counteract stomach acidity .They contain sodium bicarbonate, magnesium hydroxide, or aluminum hydroxide. Some preparations contain substances such as magnesium trisilicate that reduce the formation of gas. Antacids are in several models, ones can work better than others, usually liquids work faster but solids are also usefull.
How do antacids work?
hypothesis
our hypothesis is that mylanta is the antacid that will work better in less time because in our research we found that the liquid antacids work faster than the solid ones. we also think mylanta is the more effective because is well tolerated in the body and it doesn't cause constipation.
research
experimental procedure
materials

- 10 drops of Grape juice (no sugar added)
- 10 drops of Lemon juice
- 1 Eye dropper
- Several test tubes (3-4)
-Several different types of liquid antacids: mylanta, alka-zeltzer, gaviscon.
antacid potency
question
which antacid is more potent?
our research of antacids is about which one is more potent and effective in less time.

- The most effective in less time was a liquid antacid
- Antacids help to treat indigestion.
- antacids work by changing the stomach acid, also by reducing the stomach production of acid.
- When an acid and a base combine, the base neutralizes the acid in a chemical reaction.


objective

When an acid and a base combine, the base neutralizes the acid in a chemical reaction. This is how antacids work as well. This project will test which antacids are most potent in neutralizing lemon juice.

- Add ten drops of grape juice to each test tube.

- Rinse the eyedropper thoroughly.

- Add ten drops of lemon juice (an acid) to each test tube.

- Add the first antacid, drop by drop, to the first test tube. Stop as soon as the solution changes colors. A color change means that the antacid has neutralized the acid in the lemon juice.

- record the number of drops needed to neutralize the acid.

- Repeat this process with the remaining types of antacids, adding drops of one antacid to each of the remaining test tubes.

- Record your data.
personal interests of the experiment
The personal interests of this experiment is to help people to choose the best antacid when they have indigestion.

procedure and results

second test tube:
alka-seltzer
as a base we added
10 drops of grape juice and 10 drops of lemon juice
third test tube:
mylanta
as a base we used 10 drops of grape juice and 10 drops of lemon juice
results
The results where that mylanta was the most potent antacid. Our hypothesis was right, because as we investigated we realized that mylanta was very effective, and this experiment proves it.
firts test tube: gaviscon
as a base we added
10 drops of grape juice and
10 drops of lemon juice.

# of drops of antacid: 8 drops
- we analyzed that after 8 drops of gaviscon
the base changed into lumps and a lighter purple
# of drops of antacid: 5 drops
-we analyzed that after 5 drops of alka-seltzer the base began to create little bubbles and affected a little the color of the base.
# of drops added: 4drops
-we analyzed that afetr 4 drops of mylanta the base changed into a lighter purple and some dark spots.

conclusion
our conclusion is that mylanta was the most potent antacid. Our hypothesis was proven, we did some research and we found that the liquid antacids work faster and better than the solid ones. mylanta usually reacts better in the body than others antacids.
How this experiment applies to real life?
This experiment applies to real life because it helps people with their indigestion, when we are sick we always want to find a fast solution.
In this experiment we have the solution because we proved the faster antacid.
