A salt solution is a liquid mixture that contains dissolved salt particles. However, there are different types of salt solutions, depending on the specific type of salt used. For instance, a saline solution is a type of salt solution that contains sodium chloride, while a brine solution has a higher salt concentration and may contain other types of salts like potassium chloride or calcium chloride. An electrolyte solution is another type of salt solution that conducts electricity due to the presence of dissolved ions. The term "saltwater" is also commonly used to refer to a solution of water and salt, and may be used interchangeably with "salt solution".
