Answer by Guest. Silver nitrate is highly soluble in water and other solvents. Dispose of all chemicals as instructed (some go down the drain and some are emptied into a waste beaker). <> e. Copper(II) chloride and Sodium Hydroxide . To be sure, it's not always easy to undo a physical change, as we learn when we get an estimate from the body shop -- but I think the point of that definition is to get you to think about what you would need to do to "undo" the deposition of silver metal onto copper and get that silver back into solution as silver nitrate. The biomolecules found in the plant extract play a crucial role as stabilizing and reducing agents. The blue colour of the copper (II) sulfate solution fades. ` Qo9xHS^km6G|N.Qd&Ro7+|F}Uky@$exy+yL X&54rBNkiG,Lz~_vy \.Lr|"1FKgmE& gzK2p)v;M2 Cw light brown, black starches.
