Chapter I. Introduction
A. Background Of The Study
This experiment was performed to find out if the acidity in Coca Cola could dissolve meat. The testing was done by placing pieces of pork, chicken breast and salmon into bowls filled with Coca Cola, and observing meat for 5 days.
Coca Cola is a popular carbonated beverage that is sold in more than 200 countries. Also known as Coke, it can be purchased from vending machines, department stores and restaurants all over the world. It is normally packed and sold in bottles, cans and PET bottles. Several newer versions of Coke, like Diet Coke and Vanilla Coke, are also being sold worldwide.
The main ingredients used to produce the Coca Cola drink are carbonated drink, sugar, caffeine, phosphoric acid and some natural flavoring. The presence of phosphoric acid in Coca Cola makes the drink very acidic. It has a pH level of about 2.7. At this level of acidity, Coca Cola can dissolve the calcium in tooth enamel, chalk and limestone.
There are myths and rumours that the Coca Cola drink can actually dissolve Pork in 2 days. However, this is very unlikely because the pH of our stomach is between 1.5 and 3.5. This is because of the presence of hydrochloric acid in our stomach. Despite having pH lower than Coca Cola, our stomach still needs enzymes like pepsin to break down the food in our stomach for digestion.
B. Statement Of The Problem
Certain diseases in consuming carbonated products, such as Coca Cola, has been a problem for many people as it causes osteoporosis, for lowering calcium containment in the body, and various heart diseases for its high sugar level.
Immersing the pork, chicken breast and salmon in Coca Cola over an extended period will not dissolve the meat.
D. Significance Of The Study
E. Scope and Limitations
This study was conducted from February 19, to February 24, 2013. The experiment is limited to observation time for every variable, which are the meats. The effect on the meats could change over time, not just for few days. The acidity of Coca Cola is mainly the subject of this research.
F. Definition Of Terms
Carbonated – change with carbon dioxide.
Caffeine – a bitter, crystalline alkaloid, CHNO, present in coffee, tea, kola nuts, etc.: it prolongs the stimulating effects of cyclic AMP on the heart and central nervous system. Phosphoric Acid – A clear colorless liquid, H3PO4, used in fertilizers, detergents, food flavoring, and pharmaceuticals. Acid – any compound that can react with a base to form a salt, usually sour. PH level – the degree of acidity or alkalinity of a solution.
Chapter II - Review of Related Literature
It is proven that the acidity of carbonated drinks can dissolve calcium or such substances inside a living body, thus this experiment contains legit information about the subject.
Many have performed this experiment, being the reason of its popularity. It concerns the studies of scientists or doctors that have been researching for certain diseases caused by drinking too much soft drink.
The research mainly focuses on the substances in soda; water, sugar, caffeine, phosphoric acid, and some other flavouring. It is said that the ingredient phosphoric acid has a pH level of about 2.7.The level of this acidity is quite enough to destroy calcium properties on bones, therefore it is dangerous to consume on a large scale
For the experiment, the researcher will go through series of sites and inquire for knowledge of intelligible people who are very familiar with the subject.
Chapter III – Methodology
- 3 bowls
- Chicken Breast
- Fish (meat)
- Coca Cola
1. For this science fair project, the independent variable is the type of meat used – pork, chicken breast and fish meat. The dependent variable is if the meat immersed in the Coca Cola beverage will...
