Identify the type of coprecipitation that occurred in the following situation. (a) The precipitation of bulky precipitates (e.g. MgNH4PO4) traps significant amount of the solution in the crystalline precipitate. ____________ (b) The formation of equimolar replacement (Al, Fe) 203 during the precipitation of hydroxides in a solution containing A13+ and Fe3+ _____________ (c) The coprecipitation of soluble ions (e.g. Na+ and CI) in the solution because of the absorption of electrolytes by colloidal precipitates. _____________ (d.) Dust particles may coprecipitate as crystals grow on the surface of the dust particles. ___________ (e.) lons in the solution may be trapped inside the precipitate during the crystal growth process. ___________ Fill in the blanks with the following choices: occlusion, mechanical entrapment, surface absorption, mixed crystal formation
