This insoluble solid is called barium sulfate, BaSO4 . Dissolved barium in water occurs in the form of soluble barium compounds (compounds that dissolve well in water) such as barium nitrate and barium chloride, whereas many other barium compounds are insoluble and do not contribute barium to drinking water. Certain odors may be indicative of organic or non-organic contaminants that originate from municipal or industrial waste discharges or from natural sources. Barium hydroxide, chemically written as Ba(OH)2, is soluble in water, according to Purdue University's Bodner Research Web. At low doses, barium acts as a muscle stimulant, while .

As groundwater flows through the ground, metals such as iron and manganese are dissolved and may later be found in high concentrations in the water. Barium only occurs in one oxidation state: +2. Leakage from septic tanks and/or waste-disposal sites also can introduce bacteria to the water, and pesticides and fertilizers that seep into farmed soil can eventually end up in water drawn from a well. Barium is a naturally occurring element and that is one of the six alkaline Earth metals. Can A Laicized Priest Receive Communion, Ba(OH)2 is a strong base and HCN is a weak acid, so the salt of their neutralization reaction would be basic.
