When metal salts are burned, they emit only certain wavelengths of light, so only a few lines appear. Any color of light we see is a combination of the colors seen on the spectrum. However, sunlight or light from a projector are white light, which is a combination of ALL the colors, unlike metal salts, which would result in all the colors appearing in a continuous spectrum, also unlike metal salts.

Name two properties of metal salts?
- all metal salts are ionic compounds - many salts are soluble in water and are dissociated
What do salts produce when heated?
- some salts as NaCl can be melted - other salts as Na2CO3 are thermally decomposed, obtaining a metal oxide
What are compounds composed of a metal and a non-metal known as?
salts
What is a similarity between metals and salts?
All salts contain as a cation a metal (or ammonium).
Are calcium salts inorganic?
Some calcium salts are organic, some calcium salts are inorganic.
What happens when chloride salts are burned?
By heating many salts are melted.
What are inorganic metal salts?
Metal salts that contain no carbon except as carbonate/bicarbonate.
Is Salts made of a metal and a nonmetal?
Salts are made of metal ions and nonmetal ions.
Why do salts produce colors when heated?
The cause of the color is light (specific spectral lines) emitted by the metal from the salt at high temperatures.
Name two properties of metal salts?

What do metal oxides form?
Metal Salts + water
What are nonmetallic salts?
Practically all salts contain a metal; exceptions, for example, are ammonium salts.
What are Mineral salts?
Two main components: a metal (or ammonium) as cation and an anion.
Why are metal oxides not categorized as salts?
Salts are not only compounds of oxygen.
What do salts produce when heated?

What are compounds composed of a metal and a non-metal known as?
salts
How are metal salts produced?
Salts are the products of reactions between an acid and a base.
