Copper nitrate reaction

Cu(NO3)2(aq) + 2 NaOH(aq) → Cu(OH)2(s) + 2 NaNO3(aq)

This is a chemical reaction I'll be doing soon for my chemistry lab.
And I was wondering, since the product is blue, and as is the reactant, how can I tell I've used up all the cupric nitrate and it has all reacted?

Note: and the NaNO3 is aqueous correct ?

The copper hydroxide is insoluble and will precipitate from the solution.

After you filter it off, check that the filtrate is completely clear. If not, then there is still copper in solution, so the reaction isn't complete.

Yes, sodium nitrate is highly soluble in water.

If you remove the Cu hydroxide by filtration or decanting the reaction mix and washing, try adding a little ammonium hydroxide (household "Ammonia") to the precipitate. The result should be very colorful.
