Question
Explain why addition of NH3 or HNO3 to a saturated solution of Cu(OH)2 in contact with
solid Cu(OH), increases the solubility of the solid.
O NH3 forms a complex ion with OH-, reducing its concentration and allowing more OH- ions to
dissolve from the solid phase. HNO3 reacts with Cu2", thereby reducing the Cu2 concentration and
allowing more solid to dissolve
O NH3 forms a complex ion with Cu2, increasing the Cu2 concentration. HNO3 reacts with OH-,
thereby increasing the OH- concentration and allowing more solid to dissolve
