	RUBIDIUM - LoveToKnow Article on RUBIDIUM (Site not responding. Last check: 2007-10-16)
		Rubidium hydroxide, RbOH, is a colorless solid which is formed by the action of rubidium on water, or by the addition of baryta water to a solution of rubidium sulphate.
		Rubidium chloride, RbCI, is formed on burning rubidium in chlorine, or on dissolving the hydroxide in aqueous hydrochloric acid.
		Rubidium nitrate, RbNO,, obtained by the action of nitric acid on the carbonate, crystallizes in needles or prisms and when strongly heated is transformed into a mixture of nitrite and oxide.

	Potassium nitrate - Wikipedia, the free encyclopedia
		The liquid containing various nitrates was then converted with wood ashes to potassium nitrates, crystallized and refined for use in gunpowder.
		One of the most useful applications of potassium nitrate is in the production of nitric acid, by adding concentrated sulfuric acid to an aqueous solution of potassium nitrate, yielding nitric acid and potassium sulfate which are separated through fractional distillation.
		Potassium nitrate is also used as a fertilizer, as a model rocket propellant, and in several fireworks such as smoke bombs, in which a mixture with sugar produces a smoke cloud of 600 times their own volume.

	SAHRA - Isotopes & Hydrology
		When various sources of nitrogen compounds are mixed together in surface runoff or in a body of water, the ratio of light to heavy nitrogen isotopes in the water can be used to estimate the relative contributions of the various sources.
		Collection of nitrate on anion exchange resins eliminates the need to send large quantities of chilled water back to the laboratory, eliminates the need for hazardous preservatives, makes it easier to archive samples, and allows analysis of extremely low-nitrate waters.
		Nitrogen isotopes are often useful in determining sources of nitrate in groundwater and surface water.
