Is your assignment for an experiment that you are performing?
If it's a titration experiment then hydroxide would probably be used as an agent to indicate the presence of copper (not sure which kind though, cupric (covalent) or cuprous (monolavent)).
It's been decades since I've studied Chemistry. Alas, all my Chemistry books are in storage back in the USA, so I'm going from one of my books here, The Spectroscope and Gemmology, Anderson & Payne (1998) and extrapolating some possibilities.

thanks OIC!! LOL... its for a write up report for an experiment i performed...
