Is Cr2S3 chromium II or chromium III?

Chromium(III) sulfide is the inorganic compound with the formula Cr2S3. It is a brown-black solid.

What is the name of the compound Cr2S3?

Chromium sulfide
Chromium sulfide | Cr2S3 | 99.

What is the cation and anion of Cr2S3?

anion/cation. o Cr3+ and S2- = Cr2S3 where the salt itself has a net neutral charge. You need two Cr3+(totaling in a +6 charge) combined with three S2- (= -6 charge) to give a zero (net neutral) charged salt of Cr2S3. o The superscript charges on the cation/anion become the subscript. for anion/cation.

Is cri3 chromium II or chromium III?

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Chromium(III) iodide, also known as chromium triiodide, is an inorganic compound with the formula CrI3. It is a black solid that is used to prepare other chromium iodides.

How do you write chromium III sulfide?

How many chromium ions are in the compound chromium II nitrate?

In chromium(II) nitrate, there is one chromium ion in the formula. Chromium has a 2+ charge and nitrate has a 1- charge, so one chromium ion and two nitrate ions are in the formula to create a balance between the charges of the cation and the anion.
