Pure barium, a silvery-white metal, can only be obtained by separating barium from compounds that occur naturally. Barium iodate is a slightly soluble material in pure water (Ksp[Ba(IO3)2] = 6.510-10 at 25 C). Click 'Join' if it's correct. The more acidic the water (the lower its pH), the more soluble the barium. Ba(OH)2 is a strong base and HCN is a weak acid, so the salt of their neutralization reaction would be basic. The World Health Organization (WHO) has a slightly lower health guideline of 0.7 mg/L (or PPM) for barium in water. When salt is mixed into water, it breaks down and dissolves. (L96, L214) Health Effects: The health effects of the different barium compounds depend on how well the compound dissolves in water or the stomach contents.
