Strong salts or strong electrolyte salts are chemical salts composed of strong electrolytes. These ionic compounds dissociate completely in water. They are generally odourless and nonvolatile.
Strong salts start with Na__, K__, NH4__, or they end with __NO3, __ClO4, or __CH3COO. And most group 1 and 2 metals are salts. Strong salts are especially useful when creating conductive compounds as their constituent ions allow for greater conductivity.
