Interpretation: The name of the compound formed from K and Br atoms needs to be determined.
Concept introduction: The name of a compound containing a metal ion and oxyanion can be written such that name of cation is written first followed by the oxidation state written in Roman numbers and then the name of anion is written. The suffix depends on the charge of the anion. For example, Cl- ion has the suffix −ide which makes it chloride.
Answer to Problem 34SSC
The name of the compound
Explanation of Solution
The name of the compound in which the ions are potassium and bromine needs to be determined. Here, potassium is a cation so its name comes first followed by name of anion that is Br. Potassium has a +1 charge and bromine has a -1 charge thus, they combine in 1:1 ratio.
So, the chemical formula is
The name of a given compound
The name of the compound
