Drilling activities give these waters an opportunity to come to the Earths surface, and/or to potentially contaminate underground drinking water aquifers. Occurs naturally in soils, groundwater, and surface water. Because hydrogen sulfide is a gas dissolved in water that can easily escape or be lost from the sample, a water sample must be chemically stabilized immediately after collection in order for the laboratory to accurately measure its concentration. When barium cyanide is heated to 300 C with the steam present, the nitrogen evolves to ammonia, leaving barium formate. Low levels of certain barium compounds may have no effects on public health whatsoever. Barium is not classified as a human carcinogen.

Calculate the pH of the resulting solution. [OH-] Except where otherwise noted, data are given for materials in their standard state (at 25 C [77 F], 100 kPa). (Use H3O+ instead of H+.) barium chloride is more water soluble and more dangerous than barium carbonate), and the waters alkalinity (decreasing pH increases the potential for barium contamination). The only way to know for sure whether or not your drinking water contains this metal is to get a water sample tested. Barium sulfide slowly decomposes in water, forming barium hydroxide and barium hydrosulfide. In a titration of cyanide ion, 28.72 $\mathrm{mL}$ of $0.0100 \mathrm{M} \mathrm{AgNO}_{3}$ is added before precipitation begins. Be sure to specify states such as (aq) or (s).
