Is compound consisting of Cr3 ions and OH- ions would be named chromium(III) hydroxide.?
Yes, that is correct. When chromium ions in a compound have a +3 charge and are paired with hydroxide ions (OH-), the compound would be named chromium(III) hydroxide.
The ions Cr3 plus and O2- combine to form the ionic compound chromium oxide. In what proportions do these ions combine to produce a neutral compound?
The Cr3+ ion has a +3 charge, while the O2- ion has a -2 charge. To form a neutral compound, we need two O2- ions to balance the charge of one Cr3+ ion. Therefore, the ions combine in a 1:2 ratio to produce the ionic compound chromium oxide (Cr2O3).
Write the name of the compound Cr3 PO3 2?
Chromium (iii) Phosphite
Is Cr2O3 molecular or ionic?
Cr2O3 is an ionic compound. It consists of chromium ions (Cr3+) and oxide ions (O2-) held together by ionic bonds.
What is Cr(NO2)3?
Cr(NO2)3 is the chemical formula for chromium(III) nitrate, which is a compound consisting of one chromium ion (Cr3+) and three nitrate ions (NO2-). It is a dark red solid that is commonly used in laboratory settings for various chemical reactions.

What color is cr3 plus?
CR3+ typically refers to chromium(III) ions which are green in color.
Is Cr2O3 molecular or ionic?
Cr2O3 is an ionic compound. It consists of chromium ions (Cr3+) and oxide ions (O2-) held together by ionic bonds.
What is Cr(NO2)3?
Cr(NO2)3 is the chemical formula for chromium(III) nitrate, which is a compound consisting of one chromium ion (Cr3+) and three nitrate ions (NO2-). It is a dark red solid that is commonly used in laboratory settings for various chemical reactions.
What is the formulae of the compound formed by Cr3 plus f minus1?
The compound formed by Cr3+ and F- is chromium(III) fluoride. The chemical formula is CrF3.
What is the Oxidation number of cr plus 3?
The oxidation number of Cr in Cr3+ is +3. This is because each Cl ion has a charge of -1, and since the compound is neutral, the total positive charge from Cr must equal the total negative charge from the Cl ions.
What is the chemical formula for chromium II Phosphate?
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
Is chromium nitrate ionic or covalent?
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.
What alkaline earth metal element that crystals contains that give emearalds their green color?
Cr3+ ions
