Net Ionic Equations verification

[Pengwuino]

Ok I need some verification on this so i don't go nuts. These are all in aqueous solutions

Combine... bum bum bummmm

Magnesium nitrate and sodium hydroxide

Formula equation: Mg(NO3)2 + 2NaOH ---> 2NaNO3 + Mg(OH)2

Total Ionic eq: Mg + 2NO3 + 2Na + 2OH ---> 2Na + 2NO3 + Mg(OH)2

Net Ionic eq: Mg + 2OH ---> Mg(OH)2

Sorry, I didn't put the charges (or whatever they are called lol) but i don't know how to do superscripts.

Also, what I assume this means is that when you combine the two aqueous solutions, you will get a precipitate Mg(OH)2.

Whats the question here..

 

[Pengwuino]

need to verify that I got the equations correct.

 

[whozum]

Your ionic equatiosn are fine, your last sentence doesn't make sense.

 

[Pengwuino]

If you combine the two, won't the precipitate be Mg(OH)2

 

[whozum]

As far as I remember the hydroxide molecule is soluble in water.

 

[Pengwuino]

Doesn't look like it according to my manual

 

[whozum]

Your manual knows better than me then.
If there's a precipitate, its the magnesium hydroxide.

Man i hate this chemistry crap!
