Study Notes

Chemical Compounds

Chemical compounds are formed when atoms combine.
An oxide is a compound formed when a metal combines with oxygen
Basic oxides are formed when metals combine with oxygen.
Acidic oxides are formed when nonmetals combine with oxygen.
Bases are compounds that release hydroxide ions (OH-) when dissolved in water.
Acids are compounds that release hydrogen ions (H+) when dissolved in water.
Salts are compounds formed from the reaction of an acid and a base.
Salts are neutral compounds.

Types of Chemical Compounds

Oxides:
- Formed by the combination of a metal or nonmetal with oxygen.
- Basic oxides are formed from metals and acidic oxides are formed from nonmetals.
Bases:
- Release hydroxide ions (OH⁻) in water.
- Often contain a metal and hydroxide.
Acids:
- Release hydrogen ions (H⁺) in water.
- Often contain hydrogen and a nonmetal.
Salts:
- Formed by the reaction of an acid and a base.
- Neutral compounds.

Classification of Inorganic Compounds

Inorganic compounds are classified into oxides, bases, acids, and salts.
Examples of inorganic compounds include oxides like Na₂O, bases like NaOH, acids like HCl, and salts like NaCl.
