bromide ion metals

Identify halide ions - chloride, bromide, iodide

Halides ions are fluorides chloride, bromide, and iodide. Many halide compounds of alkali and alkali earth metals are soluble in water. These halide ion compounds exist in different forms in nature as solutions, precipitates and solids. Some halide compounds have colours which is useful to identify them. Halide compounds of Pb and Ag have colours.

Formulas and Nomenclature of Ionic and Covalent Compounds

Ionic Compounds Containing a Metal and a Polyatomic Ion. Metals combine with polyatomic ions to give ionic compounds. Name the cation first (specifying the charge, if necessary), then the polyatomic ion as listed in the table above (or as derived from the rules which were given).

Platinum compound(+2 +4 ions)? | Yahoo Answers

Nov 19, 2011· Best Answer: Just reinforce for what others already replied, Rule of compound based on their charges: Bromide has charge -1: so in order to balance charge with Pt +2, you need 2 Bromide: PtBr2 Similarly for charge +4 => PtBr4 However CO3 has charge -2: To combine with Pt +2, you need only one CO3 to balance ...


Nickel Bromide is generally immediately available in most volumes.High purity, submicron and nanopowder forms may be considered. Most metal bromide compounds are water soluble for uses in water treatment, chemical analysis and in ultra high purity for certain crystal growth applications. The bromide ion in an aqueous solution can be detected by adding carbon disulfide (CS 2) and chlorine.

Nomenclature of Binary Ionic Compounds Containing a Metal ...

A binary ionic compound is composed of ions of two different elements - one of which is a metal, and the other a nonmetal. For example, sodium iodide, NaI, is composed of sodium ions, Na + (elemental sodium is a metal), and iodide ions, I-(elemental iodine is a nonmetal). Rule 1.

Testing for Ions - Absorb Learning

Anions are negatively charged ions (so called because they are attracted to the anode – the positive electrode – during electrolysis). anions, rely on precipitation reactions.Examples include testing for halide ions (e.g. chloride, bromide, iodide), which are formed by the halogen elements

Positive and Negative Ions: Cations and Anions - dummies

Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride. A metal reacts with a nonmetal to form an ionic bond.

Metal assessment for the catalytic reduction of bromate in ...

Mar 01, 2015· The catalytic reduction under hydrogen is an attractive process for its removal by conversion into bromide ion. Different metals (Pd, Pt, Ir, Rh, Ru, Fe, Sn, Cu, Zu and Ni) supported on activated carbon were assessed for the catalytic reduction of bromate under hydrogen at room temperature and pressure.

Corrosion of Stainless Steels and Titanium in Bromide ...

Chloride ions are the most prevalent halide ions in our environment and are involved in many stainless steel corrosion failures. Bromine compounds have many important technological uses and localized corrosion caused by bromide ions is a significant problem, but one that has been less studied.

Magnesium bromide is an ionic compound with the chemical formula MgBr2. What does the "2" tell you? a. Bromide has a 2- charge b. There are two magnesium ions to every bromide ion c. There are two bromide ions for every magnesium ion d. Bromide has a 2+ charge


METHYL BROMIDE is incompatible with metals, dimethyl sulfoxide, ethylene oxide. [Lewis]. Can give flammable products if mixed with potassium hydroxide, sodium hydroxide and other strong bases. Methyl bromide in a steel tank reacted with an aluminum tube (part of the level gauge) producing methyl aluminum bromide.

Bromide - Wikipedia

A bromide is a chemical compound containing a bromide ion or ligand.This is a bromine atom with an ionic charge of −1 (Br −); for example, in caesium bromide, caesium cations (Cs +) are electrically attracted to bromide anions (Br −) to form the electrically neutral ionic compound CsBr. The term "bromide" can also refer to a bromine atom with an oxidation number of −1 in covalent ...

Group 7 of the Periodic Table – The Halogens (non-metals)

The group 7 halogens have 7 outer electrons and only need to gain one electron to form a stable negative ion, or, share one electron to make a covalent bond, thus making them the most reactive non-metals of the periodic table. The halogen atoms all have 7 outer electrons, this outer electron similarity, as with any Group in the Periodic Table ...


TESTING FOR HALIDE IONS. This page describes and explains the tests for halide ions (fluoride, chloride, bromide and iodide) using silver nitrate solution followed by ammonia solution. Using silver nitrate solution. Carrying out the test. This test has to be done in solution. If you start from a solid, it must first be dissolved in pure water.

Is bromide a nonmetal? -

The ions in potassium bromide are the potassium ion, K+, and the bromide ion, Br-. Graphite is that a metal nonmetal or a metalloid? nonmetal, because it is a form of carbon and carbon is a nonmetal.

May 09, 2000· An understanding of lithium bromide chemistry is also required. Chemistry unplugged For any corrosive process to occur chemically, two separate electrochemical reactions are required. The obvious first process is the one where the metal dissolves. The free metal gives up its electrons, becomes a positively charged ion, and goes into solution.

Metals combine with polyatomic ions to give ionic compounds. Name the cation first (specifying the charge, if necessary), then the polyatomic ion as listed in the table ...

Bromine | chemical element |

It is, however, a less powerful oxidizing agent, chiefly because of the weaker hydration of the bromide ion as compared with the chloride ion. Similarly, a metal-bromine bond is weaker than the corresponding metal-chlorine bond, and this difference is reflected in the chemical reactivity of bromine, which lies between that of chlorine and that ...

Pitting Susceptibility of Stainless Steels in Bromide ...

It is found that there is a less beneficial effect of molybdenum in solutions containing bromide ions than in those with chloride. Particular attention has been paid to the pitting behavior of UNS S31254 steel, which is found to be significantly more susceptible in bromide solutions. The effects of inclusions has also been observed on this alloy.

tion of the positive calcium ion and the negative bromide ion. Models should show that the calcium atom loses two electrons, forming Ca2, and that bromine gains one electron, forming Br. The models should also show the addition of energy to form the calcium ion, and the release of energy to form the bromide ion. Section 7.2 Ionic Bonds and Ionic
