@gandalfwiz hey ! what about the correct formula for Na+ and (SO4)2- ? isnt it Na2SO4 since 'the compound is sodium sulphate I think
OpenStudy (anonymous):
Yep, it is. When you're making ionic compounds, you switch the number for the charges, so because Sulfate has a charge of 2-, the Sodium takes on the 2 and becomes Na2SO4. Does that make sense?
