When NH₃(aq) is added to Cu²⁺(aq), a precipitate initially forms. What is its formula? A) CuO B) Cu(NH₃) C) Cu(O H)₂ D) Cu(NO₃)₂

Question

The reaction involves the combination of CuS and HNO3 to form Cu(OH)12(NO3). The sulfate ion from NH₃(aq) will then react with the copper ion to form CuSO4, which is insoluble in water and forms a precipitate. Thus, the formula of the precipitate would be CuSO4, which is closest to option C, Cu(OH)₂ (as CuSO4 can further react with water to form Cu(OH)2).
