Write the chemical formula for chromium(VI) sulfate
Sure, here's the chemical formula for chromium(VI) sulfate:
Cr(SO4)3. Why did the chemist break up with their girlfriend? Because there was no chemistry between them!
The chemical formula for chromium(VI) sulfate is Cr2(SO4)3.
To write the chemical formula for chromium(VI) sulfate, we need to determine the charges of the atoms involved and balance them to create a neutral compound.
The Roman numeral "VI" in the name tells us that chromium is in the +6 oxidation state. Sulfate ion (SO4^2-) has a charge of -2.
Let's use "x" as the subscript for chromium and "y" as the subscript for sulfate:
Chromium (Cr^6+) x
Sulfate (SO4^2-) y
To balance the charges, we multiply the Cr^6+ charge by x and the SO4^2- charge by y. Since the overall compound must be neutral, the charges must cancel each other out. Therefore, we have:
6x + 2y = 0
To simplify the equation, we divide both sides by 2:
3x + y = 0
Now, let's find the simplest whole-number ratio of x and y:
3x + y = 0
y = -3x
We can choose any value for x, but let's use x = 1 for simplicity. Therefore, y = -3(1) = -3.
Now, we substitute the values back into the formula:
Chromium (Cr^6+)1
Sulfate (SO4^2-) -3
To balance the charges and make the compound zero overall, we need three sulfate ions:
Cr2(SO4)3
Therefore, the chemical formula for chromium(VI) sulfate is Cr2(SO4)3.
Cr(SO4)3
You know all you need to do is to Google formula for Cr(VI) sulfate and up pops the formula.
