Question

Which of the following is the best name for a compound made from calcium and bromine? (CaBr2) calcium bromide calcium dibromide monocalcium dibromide calcium bromine II

Answer 1

Answer:

Calcium Bromide

Explanation:

Metals like Calcium reacts with halogens like bromine to form Metal halides.

Metal + Halogen → Metal halide

The generally accepted names for compounds and elements are the IUPAC names,

Therefore for calcium and bromine, the IUPAC name of the salt formed is calcium bromide.

Answer 2

Answer:

Calcium bromide

Explanation:

   Calcium bromide is mainly used as dense aqueous solutions for drilling fluids. It is also used in medicines, freeze mixtures and photography.

  The nomenclature follows the general rule:

                               Anion Name + Cation Name

    But this is only effective for those salts that are classified as simple salts, which means, salts that dissociate into water and form only one cation and one anion.

    When we work with a salt called double, for example, this rule goes through some adjustments.  It is one that presents in its constitution the presence of two cations accompanying an anion or two anions accompanying a cation. For this reason, when these salts undergo the dissociation phenomenon in water, they release two cations or two anions, depending on the salt with which they are working.

   The double salt that has in its constitution two cations accompanying an anion is called double salt as the cation. To name such a salt, we must use the following naming rule:

           Anion name + name of the two cations

The name of each cation is written according to the order of electropositivity. Thus, the most electropositive cation will be written first.
