Double Replacement Reactions

2 reactions in this lab were double replacement reactions that formed precipitates.

Part B was the first of these two. We started with Cu(NO3)2 and added NaOH. This formed a solid Cu(OH)2c and an aqueous solution NaNO3. The driving force was formation of a solid, and since NaOH is soluable, Na(NO3)2 formed a solid

The second precipitation reaction occured in Part E. We started with a solution of Cu(PO4)2 and added H2SO4. This formed aqueous NaCl and solid Cu3(PO4)2. The driving force in this reaction was formation of a solid and since NaCl is soluable, Cu3(PO4)2 formed a precipitate
