The crisscross method is a technique used to determine the chemical formula of a compound, including lead (II) sulphide.
How is this so?In this method, the charges of the ions involved are crossed over and used as subscripts for the opposite ion.
For lead (II) sulphide,the lead (II) ion has a charge of +2, and the sulphide ion has a charge of -2.
When crisscrossing the charges, the formula forlead (II) sulphide becomes PbS.
The crisscross method is important because it allows us to accurately determine the chemical formula of a compound, providing essential information about the composition and ratio of elements present.
