Final answer:
The question asks about the process of creating the chemical formula for an ionic compound by transposing charges into subscripts and reducing to the lowest ratio to achieve neutrality.
Step-by-step explanation:
The process described in the question pertains to determining the formula for an ionic compound. The steps outlined are part of the process to achieve the chemical formula from the given charges on the ions. Firstly, one would transpose the magnitude of the positive charge, which is typically associated with the cation, to become the subscript of the anion.
Similarly, the magnitude of the negative charge on the anion is transposed to become the subscript of the cation. This ensures that the overall charge of the compound is neutral. After transposing, it is often necessary to reduce to the lowest ratio to get the empirical formula of the compound.
For example, if we have a cation with a +2 charge and an anion with a -3 charge, transposing the charges would result in the cation having a subscript of 3 and the anion a subscript of 2, to reflect the magnitude of each charge (not considering the sign). The preliminary formula would be written as Cation3Anion2. Now, if there is no simpler ratio between the subscripts, this formula represents the empirical formula of the compound.
