What is the symbol and charge of dichromate?
The symbol for dichromate is Cr2O7^2-, indicating that it is a polyatomic ion composed of two chromium atoms bonded to seven oxygen atoms with an overall 2- charge.
What is the oxidation number of Cr is acidified potassium dichromate?
The oxidation number of Cr in acidified potassium dichromate (K2Cr2O7) is +6. This is because each oxygen atom has an oxidation number of -2, and the overall charge of the dichromate ion is -2.
What is Na2CrO4 3H2O?
Sodium chromate, a yellow crystalline solid, is the chemical compound Na2CrO4. Its hydrated form, Na2CrO4·3H2O, contains three molecules of water per molecule of sodium chromate. This compound is water-soluble and is commonly used in laboratory applications.
Name the following binary compound K2Cr2O7?
The chemical name is, potassium dichromate. It is orange in colour. Dichromate ion gives colour for this compound.
What is (NH4)2CrO7 individual ions?
When (NH4)2CrO7 dissolves in water, it dissociates into ammonium ions (NH4+) and dichromate ions (Cr2O7^2-). The ammonium ion carries a positive charge and consists of one nitrogen atom and four hydrogen atoms. The dichromate ion carries a negative two charge and consists of two chromium atoms and seven oxygen atoms.
How do you work out the valency of the dichromate radical -Cr2O7?
The dichromate ion has the charge -2.
What is the formula for patassium dichromate?
The chemical formula of potassium dichromate is K2Cr2O7
What is the symbol and charge of dichromate?

Why are there 7 oxygen's in ammonium dichromate?
The dichromate ion is Cr2O7-2. Ammonium dichromate is two ammonium ions and one dichromate ion (to balance charges- ammonium has a +1 charge and dichromate has a -2 charge): (NH4)2Cr2O7. Therefore, ammonium dichromate would contain 7 oxygen atoms.
What is the oxidation number of Cr is acidified potassium dichromate?
The oxidation number of Cr in acidified potassium dichromate (K2Cr2O7) is +6. This is because each oxygen atom has an oxidation number of -2, and the overall charge of the dichromate ion is -2.

Name the following binary compound K2Cr2O7?
The chemical name is, potassium dichromate. It is orange in colour. Dichromate ion gives colour for this compound.
What color is barium dichromate?
Due to the presence of transition metal ions i.e. Chromium(VI) ions
What is Cr charge in formula CaCr2O7?
In the formula CaCr2O7, the Cr represents chromium, specifically in its +6 oxidation state. This compound is calcium dichromate, often used as an oxidizing agent in organic chemistry reactions.
Please Help me in finding the valency of dichromate in ammonium dichromate?
The valency of dichromate ion (Cr₂O₇) in ammonium dichromate (NH₄)₂Cr₂O₇ is 6. This is because the two chromium atoms each have a valency of 6 in the dichromate ion, which is balanced by the two ammonium ions with a valency of 1 each.
Name of K2Cr2O7?
The name for K2Cr2O7 is potassium dichromate.
Symbol for dichromate?
The formula of the dichromate ion is Cr2O72-
