write net ionic equations

write the net ionic equations for the reactions which occurred when aqueous KOH was initially added to:

1)Al(NO3)3 : I think this one is souble equation.

2)Fe(NO3)3 : Fe^3+ + 3OH^- ----> Fe(OH)3

3)Ni(NO3)2 : I think this one is souble equation.

I think I am not exactly understand, so Could you please explain for me?

Thanks

All three of the reactions will produce hydroxides (Al(OH)3, Fe(OH)3, Ni(OH)2). The "net ionic equation" is simply an equation without the "spectator ions" being shown.

$Al^{3+} + 3 OH^- \rightarrow Al(OH)_3$

I really don't understand so just number 1 answer is
$Al^{3+} + 3 OH^- \rightarrow Al(OH)_3$ [/QUOTE]

this?

I don't understand sorry,

So,
these 3 quesetions answers are

$Al^{3+} + 3 OH^- \rightarrow Al(OH)_3$
$Fe^{3+} + 3 OH^- \rightarrow Fe(OH)_3$
$Ni^{2+} + 2 OH^- \rightarrow Ni(OH)_2$

Yup. That's it.
