Quick question about equation..............

Writing ionic equations, use only ions or species taking part in reaction and show aqeuos ions only.

eg.

H2SO4 + 2NaOH ---> Na2SO4 + H2O

WRITE IONIC EQUATION

2H+ + 2OH- ---> 2H2O

Do we not include the sodium because it has remained the same? (2Na ---> Na2)
And we don't include the SO4 because that has remained the same? (SO4 ---> SO4)

Is that right?

if you're writing an ionic equation, you break up all the ionic compounds into their individual ions.
so it would be H2SO4 + 2Na^+ + 2OH^- ---> 2Na^+ + SO4 ^2- + H2O

*and if you wanted the net ionic equation, you would cancel out any ions that are on oppisite sides of the arrow, so you would take out the 2Na^+

the second one- you can't write an ionic equation since it isn't an ionic equation
