Is iron a metal, nonmetal or metalloid? Is sodium chloride an amorphous solid? Is scandium a metal, nonmetal or metalloid? Is platinum a metal, nonmetal or metalloid? Is bromine a metal, nonmetal or metalloid? Is gold a metal, nonmetal or metalloid?
Which type of bond is formed when an atom of potassium transfers an electron to a bromine atom?A bond formed by mutual sharing of electrons is called: (a) Ionic bond. (b) Covalent bond (c) Co-ordinate covalent bond. (d) All of these.The...
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 solution. For more information on potentiometric titrations, related titrators and routine applications, ...
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...
If an atom has this, then this means that it is an ion. To better illustrate, in the following example, for K (potassium) ion, the __charge is +1, so the oxidation number is +1__. For Br (bromine) ion, the __charge is -1, so the oxidation number is -1__. Another example...
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 ...
conduct electricity. During electrolysis, lead ions (Pb²⁺) migrate towards the cathode (negative electrode) where they gain electrons and are reduced to form lead metal. Bromide ions (Br⁻) migrate towards the anode (positive electrode) where they lose electrons to form bromine gas (Br...
It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur when they interact with other things. The quantum mechanical approach is currently ...
(2021) reported that Spirulina sp. is highly effective in treating pollutants from aquaculture wastewater by removing bromine (96.8 %), phosphate (93.8 %) and sulphate (94.0 %), thus Spirulina sp. is identified as one of the best microalgae for pollutants amputation in wastewater. Other than ...
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) ...
