Oxygen analyzer for Plas-Labs temperature and humidity box. KCl is used as a … Dissolved oxygen can also be determined with precision using oxygen sensitive electrodes; such electrodes require frequent standardization with waters containing Compare these with the properties of an electron. In dietary supplements, potassium is often present as potassium chloride, but many other forms—including potassium citrate, phosphate, aspartate, bicarbonate, and gluconate—are also used . - Get the answer to this question by visiting BYJU'S Q&A Forum. It can explode when mixed with a strong reducing agent. 1 Answer. Potassium helps to regulate blood pressure, so taking carefully monitored amounts of potassium chloride to treat a condition of low potassium can help prevent a heart attack. It is made by electrolysis of a hot solution of potassium chloride. So, mass of oxygen formed during the reaction: Mass of reactants = 24.5 g. Mass of products = mass of the potassium chloride + mass of oxygen. Potassium chlorate and sulfuric acid react to cause fire and possible explosions [Mellor 2:315.
