Oxidants for combustion have high oxidation potential and include atmospheric or pure oxygen, chlorine, fluorine, chlorine trifluoride, nitrous oxide and nitric acid. For instance, hydrogen burns in chlorine to form hydrogen chloride with the liberation of heat and light characteristic of combustion.
Blood sodium testing is used to detect abnormal concentrations of sodium, termed hyponatremia (low sodium) and hypernatremia (high sodium). A doctor may order this test, along with other electrolytes, to identify an electrolyte imbalance.
Low sodium levels can cause a number of symptoms. Generally, symptoms include disorientation, tiredness, and headache. Muscle cramps, and nausea are other common signs of low sodium levels. If the condition remains for a prolonged period of time, coma and seizures can occur.
