I. Introduction
Salt, also known as common salt, table salt, rock salt, or halite, is an ionic compound with the formula NaCl (sodium+chloride). Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt, it is commonly used as a condiment and food preservative.
Because of its importance to survival, salt has often been considered a valuable commodity during human history. However, as salt consumption has increased during modern times, scientists have become aware of the health risks associated with high salt intake, including high blood pressure in sensitive individuals. Therefore, some health authorities have recommended limitations of dietary sodium, although others state the risk is minimal for typical western diets.
Oil is any neutral chemical substance that is a viscous liquid at ambient temperatures, is immiscible with water but soluble in alcohols or ethers. Oils have a high carbon and hydrogen content and are usually flammable and slippery (nonpolar). Oils may be animal, vegetable, or petrochemical in origin, volatile or non-volatile.
Oil is a fossil fuel. Most of the oil extracted today has been formed from prehistoric organisms whose remains settled at the bottoms of oceans and lakes millions of years ago. As layers of sediment covered them, the pressure on them increased which in turn increased the temperature. This process changed their chemical composition, eventually transforming them into oil.
II. Materials & Methods
Materials
The materials needed for this experiment are a tall clear drinking glass, 1/4 cup olive/vegetable oil, 1 or more teaspoon of salt, tap water, Food coloring (red, green, blue, and any other color you like), eye dropper(optional if your food coloring is not in a dropper).
Procedures
To start the activity, fill the glass about 2/3 full
