When barium cyanide is heated to 300 C with the steam present, the nitrogen evolves to ammonia, leaving barium formate. To calculate the actual pH, we must look at the hydrolysis of CN-. To tell if Ba(ClO4)2 (Barium perchlorate) forms an acidic, basic (alkaline), or neutral solution we can use these three simple rules along with the neutralization reaction that formed Ba(ClO4)2 .First we need to figure out the acid and base that were neutralized to form Barium perchlorate. Barium: Benzene: Benzidine: Benzo . Highly water-soluble barium compounds have more serious health risks than barium compounds with a low water solubility. Cyanide is mainly metabolized into thiocyanate by either rhodanese or 3-mercaptopyruvate sulfur transferase. Destroys testicular tissue and red blood cells. Low-pH water will corrode or dissolve metals and other substances. Official websites use .gov 8H2O It's impossible to tell the exact pH without any concentrations, but based on this (no pun intended), the solution would definitely be basic, or having a pH above 7. Although I am not pretty sure about this fact, but the following are insoluble in water despite being a nitrate/sodium salt. What is Soluble and Insoluble ?

Barium is a metallic alkaline earth metal with the symbol Ba, and atomic number 56. . Affects red blood cell chemistry; delays normal physical and mental development in babies and young children. Barium cyanide reacts with water and carbon dioxide in the air slowly, producing highly toxic hydrogen cyanide gas. Barium oxide will further react with water to produce barium hydroxide. Calculate the pH of the resulting solution. Freshwater and saltwater criteria for metals are expressed in terms of the dissolved metal in the water column. There may be formed a white precipitate of barium carbonate, which if filtered off, washed and treated with acid, will dissolve with effervescence. Barite, a naturally occurring barium compound, is a common component of drilling fluids, or muds, used to aid the drilling process. These low levels of barium are not harmful, however, large quantities of soluble barium salts can be toxic and even deadly. That having been said, here is a table of solubility product .
