Please show the chemical formula of Hydrogen Sulfate by Criss-Cross Method.. As Using Criss-Cross Method it comes out to be H2SO4 but in Google it is written HSO4
The criss-cross method is a technique used to determine the chemical formula of an ionic compound. In the case of hydrogen sulfate, it is an ionic compound made up of hydrogen ions (H+) and sulfate ions (SO42-).
To use the criss-cross method, you simply write down the ion charges and switch them to make subscripts.
H+ has a charge of +1
SO42- has a charge of -2
To balance the charges, you need two hydrogen ions and one sulfate ion:
H2SO4
Therefore, the correct formula for hydrogen sulfate by the criss-cross method is H2SO4. It's possible that HSO4 is used as a shorthand way to represent hydrogen sulfate in some instances, but the correct formula is H2SO4.
