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.
Which polyatomic ion has 4 oxygens?
The three most common such ions probably are sulfate, with the formula SO4-2, chromate, with the formula CrO4-1, and perchlorate, with the formula ClO4-1.
How do you write lead IV hydroxide?
The chemical formula of lead(IV) chromate is PbCrO4.
What are the oxidation numbers for CrO4-2?
Charge of CrO4 is -2
What is the chemical formula for chromate plus charge?
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 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.
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.
What is the ionic charge of sodium?
The chemical formula of sodium chromate is Na2CrO4. The sodium cation is Na+ and the chromate anion is (CrO4)2-.
How many moles of chromate ions are present in a sample that contains 3.71 moles of iron-III- chromate Fe2-CrO4-3. Dashes are parentheses.?
Fe2(CrO4)3 3.71 moles Fe2(CrO4)3 (3 moles CrO4/1 mole Fe2(CrO4)3) = 11.1 moles of chromate
What is the formula for aluminum dichromate?
