how do i know what the ions present are of this formula:
Na3PO4
what are the anions and what are the cations? how do you know
10 answers
it is based on the placement of the element on the periodic table
can you explain more? i put the cation was Na3+ and the anion was PO4-. but it said it was wrong. what am i doing wrong?
Na is +1 and is the cation and PO4- is a polyatomic ion and the anion the placement always goes to your noble gases in column VIIIA (18)
I put Na+ as the cation and it counted it wrong. also. are you saying PO4- is the anion? cause i got it wrong.
and what do the noble gases have to do with the ions.
sorry im asking many questions
and what do the noble gases have to do with the ions.
sorry im asking many questions
total you have 3 Na ions and 1 PO4- ions...so all together 4 ions
it says those answers are wrong
I don't know then...unless it is separating out each element...then it will have Na=3 P=1 and O=4...then it would be your 3 anions and 5 cations
this is what it says:
For the soluble compounds, write the ions present in solution.
this is the soluble compound:
Na3PO4
then it has 2 boxes one called cations and one called anions
For the soluble compounds, write the ions present in solution.
this is the soluble compound:
Na3PO4
then it has 2 boxes one called cations and one called anions
C'mon you guys.
Na3PO4 ==> 3Na^+ + PO4^-3
The cation is Na^+ (it has a charge of +1) and there are three of them. The anion is phosphate, PO4^-3 and it has a charge of -3.
What do noble gases have to do with ions. The simple ones, such as Na^+, are isoelectronic with the nearest noble gas.
