What is the formula for copper(ii) phosphate? capitalization and punctuation count!?
iVinArrow [24]
Hello!

The formula for Copper (II) Phosphate is

Cu₃(PO₄)₂

To know how to write this formula we go from left to right. First, Copper (II). It means that the formula has the Cu⁺² ion. Now, Phosphate means that the compound has the PO₄⁻³ ion. Now we combine this two ions, giving to each one the coefficient with the number of the electric charge of the other (e.g. to Cu⁺² we'll give the charge of PO₄⁻³ which is 3 and the result will be Cu₃⁺²). 

The combination gives us the result Cu₃(PO₄)₂

Have a nice day!
