Lewis structure of H3PO4

Postby Ivanna_Tang_3B » Fri Oct 21, 2016 4:40 pm

Is it more accurate to draw the Lewis structure of H3PO4 with ionic bonds since PO4^3- is a polyatomic ion, or better to draw it with covalent bonds?

Thank you!

It's probably more accurate to draw it the second way, just because that's how the molecule works normally, and the first method is more for two molecular ions rather than a single element and a molecule (eg (nh3)3PO4)
