Cu(NO3)2(aq) + 2NaOH(aq) --> Cu(OH)2(s) + 2NaNO3(aq)

Kathleen also measures at eye level to get the most accurate measurement of NaOH to add to our mixture



The blue cupric nitrate solution from our first reactions reacts with NaOH(aq) and produces a blue cupric hydroxide and sodium nitrate. This reaction was also one of our double replacement reactions! The Copper reacted with the Hydroxide and the Sodium reacted with the Nitrate. The driving force for this DR reaction was the formation of the precipitate (solid). This was brought on because of when together Sodium and Nitrate are insoluble.


Yay for blue! Our acidity is right on track!
