1. net ionic equation for the reaction between silver nitrate and the arsenate ion

I got:
3Ag (+) + AsO4 ---> Ag3AsO4

2. net ionic equation for the precipitation of copper hexacyanoferrate (II).

I got:
2Cu (2+) + [Fe(CN)6] ---> Cu2 [Fe(CN6)]

Can someone please check and see if I did these correctly. If not, can you please example how/ what I am doing wrong.

• Chemistry -

The total electrical charge on the left side of a chemical equation must be equal to the total electrical charge on the right side. That is not the case on either chemical equation as you typed it.

• Chemistry -

The Ag3AsO4 equation is ok if we assume the ---(which looks like an arrow with the >) is actually the charge on the arsenate ion. You can write AsO4^3- and that way we don't confuse it with the arrow.
3Ag^+1 + AsO4^3- ==> Ag3AsO4(s)

• Chemistry -

Oh sorry I forgot to write the charges.

For then for the second one,

it is supposedly look like this?
2Cu (2+) + [Fe(CN)6]^(4-) ==> Cu2 [Fe(CN6)]

would that make this ionic equation correct?

• Chemistry -

That looks ok to me.
