What is the chemical formula of a compound that is composed of the ions Ca2+ and Br-?
Understanding the Chemical Formula
In order to determine the chemical formula of a compound composed of the ions Ca2+ and Br-, we first need to understand the oxidation states of each ion.
Calcium ions have an oxidation state of 2+ represented as Ca2+. On the other hand, bromide ions carry an oxidation state of 1- signified as Br-.
For the compound to be electrically neutral, it must have two bromide ions for every calcium ion present. This relationship is shown in the chemical formula as CaBr2, where the subscript '2' next to Br indicates that there are two bromide atoms for every calcium atom.
Therefore, the chemical formula for the compound composed of Ca2+ and Br- ions is CaBr2.
What is the correct chemical formula for the compound containing Ca2+ and Br- ions? The correct chemical formula for the compound with Ca2+ and Br- ions is CaBr2.
