Gas Laws

Common Name: Pearl

Scientific Name: Calcium Carbonate

Formula: CaCO3

Fundamental particles: Pearls are comprised of a positive Calcium ion (Ca+) and a negative Carbonate polyatomic ion (CO3+)

Usage: Jewelry

Properties: Pearls are good jewelry because they are hard and lustrous. Pearls are hard because of the strong Intermolecular forces created between the Calcium and the Carbonate ions. The pearls luster is dependent on the amount of nacre excreted. The Oyster produces nacre when it is trying to neutralize a foreign particle within it.

Common Name: Milk of Magnesia

Scientific Name: Magnesium Hydroxide

Formula: Mg(OH)2

Fundamental particles: Milk of Magnesia is comprised of a positive Magnesium ion (Mg+) and two negative Hydroxide ions (OH-)

Usage: Milk of Magnesia is used to combat constipation and difficulties resulting from too much stomach acid.

Properties: Because it contains hydroxide, Milk of Magnesia is able to lower the acidity of the stomach by neutralizing some of the acid. It works as a laxative by drawing in water from the intestines.

Common Name: Baking Soda

Scientific Name: Sodium Bicarbonate

Formula: NaHCO3

Fundamental particles: Baking Soda is comprised of one Sodium ion (Na+) and one Bicarbonate ion (HCO3-)

Usage: Baking Soda has many uses; it can be used in cooking as well as cleaning, as an antacid and can also be used to fight odors.

Properties: Baking Soda is odorless and can be used as an antacid because of the Bicarbonate ion.

Common Name: Antacids

Scientific Name: mainly metal hydroxides

Formula: MOH

Fundamental particles: Antacids are comprised of one metal ion and one or more Hydroxide ions.

Usage: Antacids are used to neutralize stomach acid.

Properties: The hydroxide ions bond with the hydrogen of an acid to neutralize it.
