Salts are the products of reactions between an acid and a base.
Metal salts produced when heated can display a variety of colors, which are often characteristic of the specific metal ion present. For example, copper salts can produce blue or green colors, while potassium salts may yield purple or lilac hues. The color observed is due to the absorption of specific wavelengths of light by the metal ions in their heated state.

The electromagnetic spectrum encompasses all forms of electromagnetic radiation, which includes visible light. When metal salts are combusted, they emit specific wavelengths of light due to electronic transitions in the metal ions, leading to characteristic colors. This phenomenon allows the identification of different metal salts based on their spectral emissions, effectively linking the combustion of these salts to the electromagnetic spectrum. Thus, the colors produced by burning metal salts correspond to distinct regions within the visible spectrum.
Sulfuric acid can form salts by reacting with metals, metal oxides, metal hydroxides or metal carbonates. Some common salts produced from sulfuric acid include sulfates such as sodium sulfate (Na2SO4), copper sulfate (CuSO4) and zinc sulfate (ZnSO4).
Hydrogen gas is produced when a metal reacts with a dilute acid. This reaction occurs when the metal displaces hydrogen from the acid, forming metal salts and releasing hydrogen gas as a byproduct.
Salts are made of metal ions and nonmetal ions.
Metal salts that contain no carbon except as carbonate/bicarbonate.
When metals react with halogens, they typically form ionic salts known as metal halides. In this reaction, the metal donates electrons to the halogen, resulting in the formation of positive metal cations and negative halide anions. For example, when sodium (a metal) reacts with chlorine (a halogen), it produces sodium chloride (NaCl). The general formula for these salts is often represented as MX, where M is the metal and X is the halogen.
- all metal salts are ionic compounds - many salts are soluble in water and are dissociated
Two main components: a metal (or ammonium) as cation and an anion.
Metal Salts + water
Practically all salts contain a metal; exceptions, for example, are ammonium salts.
