    Part a please Question 3 (30 pts) Lead nitrate (Pb(NO3)2) is a toxic compound used in lead paints in the past. It has far less use now, in specialized applications such as gold extraction. Unlike most lead salts, lead nitrate is soluble in water, as seen below in the solubility chart. After aqueous gold recovery, it is desired to recover the lead nitrate from the water via crystallization. A 70°C aqueous lead nitrate solution containing 50 wt% lead nitrate and...
