How do you write the ionic formula for nickel II chromate?
The ionic formula for nickel(II) chromate is NiCrO4. This is because nickel has a 2+ charge (from the Roman numeral II in its name), and chromate is a polyatomic ion with a 2- charge, so the formula is Ni2+ and CrO4^2-.
Is fe2(cro4)3 a strong electrolyte?
Iron chromate is insoluble in water.
What chemical compound is aluminum chloride?
Al4Cl The compound name is Aluminum Chloride. Al=3- Cl=1+ Chlorine has 7 valence electrons and gains one to become stable making it a positive one charged ion. Aluminum has 3 valence electrons and loses three to become stable making it negative three charged ion.
What is the formula of chromium ion?
The formula of chromium ion depends on its charge. For example, chromium in the +3 oxidation state forms the chromic ion (Cr3+), while chromium in the +6 oxidation state forms the chromate ion (CrO4^2-).
What is the symbol and charge for the ion chromate?
The formula for a chromate ion is CrO4-2, and its charge is -2.
What is the symbol or formula including the charge for chromate ion?
The formula, including the charge, for a chromate ion is CrO4-1.
What is the chemical formula for chromate plus charge?
CrO4-2
What are the oxidation numbers for CrO4-2?
In CrO4^2-, the oxidation number for Cr (chromium) is +6 and for O (oxygen) is -2. The overall charge of the ion is -2, so the sum of the oxidation numbers must equal -2.
Chromate an anion or cation?
Chromate is an divalent anion with formula CrO4-2
What is the formula for tin (IV) chromate?
Sn(CrO4)2 Tin 4 means that the tin is a cation with a +4 charge. Chromate is a polyatomic ion with the formula (CrO4)-2. Since the tin ion has a +4 charge in this case, and the chromate ion has a -2 charge, there is a 1:2 ratio of tin ions to chromate ions.
What is the oxidation number of CrO4-2?
The oxidation number of Cr in CrO4^2- is +6. This can be calculated by considering the overall charge of the ion (-2) and the known charge of the oxygen ion (-2 each).
Is Pb(CrO4)2 a molecular compound?
No. It is an ionic compound composed of the lead IV cation (Pb4+) and the chromate anion (CrO4)2-.Pb4+ + 2(CrO4)2- --> Pb(CrO4)2
What is the formula of Copper III Chromate?
The formula for Copper (II) Chromate is CuCrO4.The copper has a 2+ charge (Cu2+) and the chromate ion has a 2- charge ( (CrO4)2-).Since the charges balance each other out, therefore, we get CuCrO4.
