Fatal dose of barium chloride for a human has been reported to be about 0.8-0.9 g. Systemic effects of acute barium chloride toxicity include abdominal pain, diarrhea, nausea, vomiting, cardiac arrhythmia, muscular paralysis, and death. Once we did that, we simply had to balance the other element (Na) which was odd on both sides, and the equation was easily balanced. H= change in enthalpy Dichromate(VI) ions (for example, in potassium dichromate(VI) solution) can be reduced to chromium(III) ions and then to chromium(II) ions using zinc and either dilute sulfuric acid or hydrochloric acid. Once a hydrogen ion has been removed from three of the water molecules, you are left with a complex with no charge - a neutral complex. These change color in the presence of an oxidising agent.
