I'm not sure. But my wife had a college professor who pronounced cation as "cay-shun" instead of "cat-ion" and called anions "an-yuns" instead of "an-ions." How that person got a PhD without ever learning ot say basic words is beyond me...
Could you rephrase and resubmit your question. This cannot be answered the way it is written. Please be specific. This way you get the best answer possible.
in CuS (Copper II sulfide) the charge on the copper ion is 2+
copper is positive 2 and sulfate is negative 2
CuSO4 is a neutral compound made from two ions which are Cu2+ and SO42- .
copper sulphate
copper(II) cation
sulfur anion
Cu2+ SO42-
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper (II) sulfate.
The Sulfate, SO4
The species in question is the sulfate ion, which has a 2- charge. It is thus properly written as SO42-
The sulfate ion is SO42-. Elements in group 16 form anions with a charge of 2-, for example oxygen forms the oxide, O2- anion.
Sulfate is a negative ion with the formula SO42- in order to balance the charge there needs to be a positive ion, which usually is a metal ion, but not always. However, the sulfate ion itself is not a metal nor does it contain a metal.
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper (II) sulfate.
The Sulfate, SO4
Copper (II) Sulfate, is an ionic compound. If that is what you are asking. Anytime you have a metal that has a number in parenthesis after it, you're going to be using ions. The number in paranthesis is what indicates the charge on the ion. For example, Copper (II) would have a charge of +2.
Copper is a single element so it is nonpolar. A polar substance forms when two or more elements with different electronegativities bond form a compound.
Since Oxygen has an ion charge of -2 & Copper has a 2 as a subscript, it means that Copper's ion charge will be +1. Cu2O = Copper (I) Oxide
Sodium sulfite, it is balanced because the sulfite ion has a -2 charge an there is two sodium ions to match it so the equation would look like so; 2 Na + SO3-2 --> NaSO3 :) Hope that helps!!
copper sulfate's chemical symbol is actually CuSO4 ... the symbol CuSO4-5H2O is copper sulfate pentahydrate... someone should edit the answer on CuSO4 copper sulfate
Sulfate ion is SO42-, so the charge is -2.
Nothing; it stays unchanged in the sulfate ion.
The species in question is the sulfate ion, which has a 2- charge. It is thus properly written as SO42-
The sulfate ion is SO42-. Elements in group 16 form anions with a charge of 2-, for example oxygen forms the oxide, O2- anion.
A molecule of CuSO4 (Copper Sulphate) contains 1 atom of Copper, 1 atom of Sulphur and 4 atoms of Oxygen. The Sulphur and the Oxygens are bound together as a Sulphate Ion.
