Sodium and Chlorine (aka: SodiumChloride or NaCl)
Salt has two properties 1) Physical Property and 2) Chemical property:) :)
- all salts are ionic compounds
- generally salts are solids
- salts are ionic compounds
- salts are generally the products of a neutralization reaction between an acid and a base
- solid salts are electrically non-conductive
- all metal salts are ionic compounds - many salts are soluble in water and are dissociated
no
YES
There are two elements. Those are sodium and chlorine.
The electrical properties of salts are very different.
Salts are made of a combination of halogen atoms and alkali metal atoms. These atoms have specific properties. If they combine with other atoms, however, and they make salts, then these salts have different properties than the atoms that make them. For example, sodium chloride is probably the most famous salt. Sodium is a soft, reactive metal and chlorine is a greenish gas (which, if possible, is even more reactive than sodium), but sodium chloride is a white and extremely nonreactive solid.
he properties of salts are different from the properties of elements that go into making them
Dissolved salts have an influence on the physical, chemical and biological properties of the solution.
water and acid
Examples: water solubility, pH of the solution, density.
- salts are ionic compounds - salts are products of neutralization reactions
Epsom salts are used for sore muscles in athletes and others. These Epsom salts have drying and pain relief properties. They can also be used as laxatives when ingested.
