The chemical formula is Cr(OH)3 and the compound is called chromium hydroxide.
This hydroxide is soluble in water.
Chromium hydroxide is a toxic substance, as many other chromium compounds.
chromium(III) hydroxide
Chromium (III) hydroxide
CrOH3 is called Chromium Hydroxide.
Chromium(III) hydroxide, Cr(OH)3.
Chromium (iii) Phosphite
Chromium (III) nitrate is formed by the reaction between Cr3+ ions and NO3- ions. Thus, forces of attraction due to disparity of charges causes this reaction. As such, we can safely say this is an ionic compound because it is formed by ions.
CrF3
Cr+2 P-3 ----> these are the ions and their charges. You know chromium's charge because of the roman numeralCr+2 Cr+2 Cr+2 P-3 P-3 ------> the charges have to add up to zero, so three +2 Cr ions plus two -3 P ions cancel each other outCr3P2 -----> simplify
Some metals can have multiple different charges, so a number after the name is given to tell what charge it has. Whereas Bromide on the other hand always has the same change (-1.) In this case you have a Chromium with a 2+ charge, and would then need 2 Bromide ions to make the compound neutral. Thus the formula is CrBr2.

CrF3
Cr3+. It's an oxidation of chromium. The anion is hydroxide.

Chromium chloride can is either CrCl3 or CrCl6. A salt is usually uncharged since the cation (here Cr3+ or Cr6+) and the anion (Cl-) combine to neutralise the charges and form a salt. Some salts can have some covalent characteristics though, but in this case both compounds above are neutral.
The answer from my chem class states its Cr(NO3)2
What volume of 0.1125 M K2Cr2O7 would be required to oxidize 48.16 mL of 0.1006 M Na2SO3 in acidic solution? The products include Cr3+ and SO42- ions.
The most important cation of chromium is Cr3+; but also exist Cr3+, Cr6+, Cr1+, Cr4+, Cr5+.
cr3
