Ionic equations- I need help!

Hi,
does anyone know how to write the ionic equation for:
Sodium hydroxide + sulphuric acid -> ?
I know that ? is sodium hydrogen sulphate (NAHS04) and H20 but I am unsure of the overall ionic equation. Could someone help?
Thank you

This may be wrong but don't you:
1) write out equation using chemical symbols
2) split all the compounds into the ions that they form
3) cross out the ions that don't change on either side of the equation??

Na⁺ + OH^- + 2H⁺ + SO₄^2- --> Na⁺ + H⁺ + SO₄^- + H₂0

Na⁺ + OH^- + 2H⁺ + SO₄^2- --> Na⁺ + H⁺ + SO₄^2- + H₂0

H⁺ + OH^---> H₂0

(sorry I just realised that this is an A Level thread... my GCSE knowledge may be useless here)

2\mathrm{Na}^{+} +2 \mathrm{OH}^{-} + 2\mathrm{H}^{+} +\mathrm{SO}_{4}^{2-} \rightarrow 2\mathrm{H}_{2} \mathrm{O} + 2\mathrm{Na}^{+} +\mathrm{SO}_{4}^{2-}

.

We can cancel unmodified species, so,

2 \mathrm{OH}^{-} + 2\mathrm{H}^{+} \rightarrow 2\mathrm{H}_{2} \mathrm{O}

, or, dividing by 2,

\mathrm{OH}^{-} + \mathrm{H}^{+} \rightarrow \mathrm{H}_{2} \mathrm{O}

.

States need to be written, in this case all species are aqueous, besides for water which is a liquid.

I didn't read the question properly. Nevermind.

Ok thanks anyway, does anyone else know how to answer the question?
