Compounds that exist as molecules are called molecular compounds. An ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or ...
across the analyte — typically an electrolyte solution — using reference and indicator electrodes. Hydrogen, calomel, and silver-chloride electrodes are often used for the reference, while a specialized titration electrode forms an electrochemical half-cell with the interested ions in the test ...
The valence electronic configuration of bromine is 4s24p5. Indicate whether the following statement is true or false: If an electron configuration ends with 5s2 4d5, the atom must have a total of 53 electrons. If the atomic number of an element is 16, then it has 16 ...

Bromine extn. from salt solns. contg. bromide ions - where bromine is extracted by air and collected in satd. ammonium bromide soln., producing ammonium poly:bromide(s)Stream of air is fed through a salt soln. (a) to remove bromide, which is then conc. in a cold conc. soln. (b) ...
A close-up of a halogen lamp A halogen lamp, also known as a tungsten halogen lamp or quartz iodine lamp, is an incandescent lamp that has a small amount of a halogen such as iodine or bromine added. The combination of the halogen gas and the tungsten filament produces a halogen cycle ...
Ozone depletion is caused by chemicals containing the elements chlorine and bromine, which are halogens. They are important components of a class of refrigerants called chlorofluorocarbons (CFCs) that were in heavy use in the mid 20th century. CFCs are inert and able to migrate to the upper atm...
