In step 2 of the experimental procedure, you added 6 M sodium hydroxide to the copper(II) nitrate solut form copper(II) hydroxide. You added a minimum amount of sodium hydroxide, but enough to complete reaction. How do you determine that enough sodium hydroxide has been added

The solution becomes colorless and a light blue precipitate is formed.

Explanation:

When sodium hydroxide is added to copper(II) nitrate solution, a precipitate of  copper(II) hydroxide is formed.

The solution gradually becomes colorless as the light blue precipitate appears.

The reaction is complete (enough sodium hydroxide has been added) when the blue color of the solution completely disappears.

The equation of the reaction is;

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