Ammonium chromate/Formula

What is the formula and charge for ammonium?

The ammonium cation is a positively charged polyatomic ion with the chemical formula NH+4.

What are the ions present in Ammonium chromate?

Ammonium dichromate is an inorganic compound with the formula (NH4)2Cr2O7. In this compound, as in all chromates and dichromates, chromium is in a +6 oxidation state, commonly known as hexavalent chromium. It is a salt consisting of ammonium ions and dichromate ions.

What is the empirical formula for ammonium chromate?

The ammonium (N H X 4 X +) cation has a charge of +1 and the chromate (C r O X 4 X 2 −) anion has a charge of -2. Since the formula unit has to have a net charge of zero, it follows that “ammonium chromate” must have the empirical formula of ((N H 4 +) X 2 C r O X 4 X 2 −).

What kind of charge does ammonium sulfide have?

The ammonium ion has a 1+ charge and the sulfide ion has a 2− charge. Two ammonium ions need to balance the charge on a single sulfide ion. The compound’s name is ammonium sulfide. b. The ions have the same magnitude of charge, one of each (ion) is needed to balance the charges.

Do you use Roman numerals for ammonium chromate?

Prefixes such as mono-, di-, tri- etc. are typically used in naming covalent/molecular compounds, and not for ionic compounds. Ammonium chromate is an ionic compound, so the prefix is not used. The ammonium cation has only a 1+ charge and so the Stock system of Roman numerals is not required.

Why is ammonium chromate not called ammonium cation?

Ammonium chromate is an ionic compound, so the prefix is not used. The ammonium cation has only a 1+ charge and so the Stock system of Roman numerals is not required. Thus, the only correct name would be ammonium chromate. Thanks for contributing an answer to Chemistry Stack Exchange!
