Barium Chloride Dihydrate
NATIONAL TOXICOLOGY PROGRAM Technical Report Series No. 432 TOXICOLOGY AND CARCINOGENESIS STUDIES OF BARIUM CHLORIDE DIHYDRATE (CAS NO. 10326-27-9) IN F344/N RATS AND B6C3Fl MICE (DRINKING WATER STUDIES) U.S. DEPARTMENT OF HEALTE AND HUMAN SERVICES Public Health Service National Institutes of Health FOREWORD The National Toxicology Program (NTP) is made up of four charter agencies of the U.S. Department of Health and Human Services (DHHS): the National Cancer Institute (NCI), National Institutes of Health; the National Institute of Environmental Health Sciences (NIEHS), National Institutes of Health; the National Center for Toxicological Research (NCTR), Food and Drug Administration; and the National Institute for Occupational Safety and Health (NIOSH), Centers for Disease Control. In July 1981, the Carcinogenesis Bioassay Testing Program, NCI, was transferred to the NIEHS. The NTP coordinates the relevant programs, staff, and resources from these Public Health Service agencies relating to basic and applied research and to biological assay development and validation. The NTP develops, evaluates, and disseminates scientific information about potentially toxic and hazardous chemicals. This knowledge is used for protecting the health of the American people and for the primary prevention of disease. The studies described in this Technical Report were performed under the direction of the NIEHS and were conducted in compliance with NTP laboratory health and safety requirements and must meet or exceed all applicable federal, state, and local health and safety regulations. Animal care and use were in accordance with the Public Health Service Policy on Humane Care and Useof Animals. The prechronic and chronic studies were conducted in compliancewith Food and Drug Administration(FDA) Good Laboratory Practice Regulations, and all aspects of the chronic studies were subjectedto retrospective quality assurance audits before being presented for public review. -

Net Ionic Equation Worksheet Answers
Honors Chemistry Name__________________________________ Period_____ Net Ionic Equation Worksheet READ THIS: When two solutions of ionic compounds are mixed, a solid may form. This type of reaction is called a precipitation reaction, and the solid produced in the reaction is known as the precipitate. You can predict whether a precipitate will form using a list of solubility rules such as those found in the table below. When a combination of ions is described as insoluble, a precipitate forms. There are three types of equations that are commonly written to describe a precipitation reaction. The molecular equation shows each of the substances in the reaction as compounds with physical states written next to the chemical formulas. The complete ionic equation shows each of the aqueous compounds as separate ions. Insoluble substances are not separated and these have the symbol (s) written next to them. Water is also not separated and it has a (l) written next to it. Notice that there are ions that are present on both sides of the reaction arrow –> that is, they do not react. These ions are known as spectator ions and they are eliminated from complete ionic equation by crossing them out. The remaining equation is known as the net ionic equation. For example: The reaction of potassium chloride and lead II nitrate Molecular Equation: 2KCl (aq) + Pb(NO3)2 (aq) -> 2KNO3 (aq) + PbCl2 (s) + - 2+ 3– + – Complete Ionic Equation: 2K (aq) + 2Cl (aq) + Pb (aq) + 2NO (aq) -> 2K (aq) + 2NO3 (aq) + PbCl2 (s) - 2+ Net Ionic Equation: 2Cl (aq) + Pb (aq) -> PbCl2 (s) Directions: Write balanced molecular, ionic, and net ionic equations for each of the following reactions. -

Toxicological Profile for Barium and Barium Compounds
TOXICOLOGICAL PROFILE FOR BARIUM AND BARIUM COMPOUNDS U.S. DEPARTMENT OF HEALTH AND HUMAN SERVICES Public Health Service Agency for Toxic Substances and Disease Registry August 2007 BARIUM AND BARIUM COMPOUNDS ii DISCLAIMER The use of company or product name(s) is for identification only and does not imply endorsement by the Agency for Toxic Substances and Disease Registry. BARIUM AND BARIUM COMPOUNDS iii UPDATE STATEMENT A Toxicological Profile for Barium and Barium Compounds, Draft for Public Comment was released in September 2005. This edition supersedes any previously released draft or final profile. Toxicological profiles are revised and republished as necessary. For information regarding the update status of previously released profiles, contact ATSDR at: Agency for Toxic Substances and Disease Registry Division of Toxicology and Environmental Medicine/Applied Toxicology Branch 1600 Clifton Road NE Mailstop F-32 Atlanta, Georgia 30333 BARIUM AND BARIUM COMPOUNDS iv This page is intentionally blank. v FOREWORD This toxicological profile is prepared in accordance with guidelines developed by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA). The original guidelines were published in the Federal Register on April 17, 1987. Each profile will be revised and republished as necessary. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the hazardous substance described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a hazardous substance's toxicologic properties. Other pertinent literature is also presented, but is described in less detail than the key studies. The profile is not intended to be an exhaustive document; however, more comprehensive sources of specialty information are referenced. -

Barium Sulfate (Blanc Fixe) CAS No
Product Safety Summary Barium Sulfate (Blanc Fixe) CAS No. 7727-43-7 This Product Safety Summary is intended to provide a general overview of the chemical substance. The information on the summary is basic information and is not intended to provide emergency response information, medical information or treatment information. The summary should not be used to provide in-depth safety and health information. In-depth safety and health information can be found in the Safety Data Sheet (SDS) for the chemical substance. Names Barium sulfate (sulphate) Blanc Fixe Product Overview Solvay Fluorides, LLC does not sell barium sulfate directly to consumers. The barium sulfate sold by Solvay Fluorides, LLC is used in industrial applications and processes. Barium sulfate is used primarily as a whitening agent or as a support for other chemicals in industrial applications. Barium sulfate is sold as an odorless white solid. Barium sulfate is a relatively non-hazardous chemical. Any hazards are due primarily to the physical form (particles). Repeated or prolonged contact can irritate the skin and eyes. Breathing barium sulfate particles can irritate the nose and throat and restrict breathing (shortness of breath). Ingestion of large amounts of barium sulfate typically does not cause any problems. Manufacture of Product Solvay Fluorides, LLC imports the barium sulfate it sells from a Solvay affiliate in Europe. Solvay manufactures barium sulfate from barium containing ore. Barium is extracted from the ore as barium sulfide. The barium sulfide is reacted with sodium sulfate to form barium sulfate. The barium sulfate is further dried and purified to form the final product.
