# Do you get a new chemical compound if you mix sodium hydroxide and water?

Me and dad started fighting over this a couple of days ago and wagered on this.

He said mixing these two gives a chemical compound, I said that it doesn't.

• Is what a chemical compound? The mixture? – f'' Aug 7 '16 at 17:36
• Is it a chem compound the mixture of water and sodium hydroxyde. – Alek Aug 7 '16 at 17:41
• Then you are right. NaOH is a compound, so is H2O, but their mixture isn't. – Ivan Neretin Aug 7 '16 at 18:09
• We need the exact sentence for your bet, because it is more tricky than you (and your father) think. – SteffX Aug 7 '16 at 18:21
• How much was the wager? – Todd Minehardt Aug 8 '16 at 1:09

According to Oxford's dictionary of chemistry "A compound is a mixture of two or more elements in a fixed ratio". So if $\ce{NaOH}$ (in solid state) is added to water, it just dissociates into its constituent ions that are $\ce{Na+}$ and $\ce{OH-}$. You can add any ratios of two until you cannot add any more.
