if actual amount of alum obtained from 2.535 grams of aluminum sulfate is 3.509g. what is the percent yield of alum?

Solutions

Expert Solution

K2SO4 + Al2(SO4)3. + 24H2O --------------------> K2SO4 Al2(SO4)3.24H2O

                     342.1 g                                                  948.77 g

                      2.535 g                                                       ?

alum thereotical mass = 948.77 x 2.535 / 342.1

                                   = 7.030 g

percent yield of alum = actual x 100 / hereotical

                                   = 3.509 x 100 / 7.030

                                  = 49.9 %

One method of removing phosphate from wastewater effluent is to precipitate itwith aluminium sulfate (alum). A possible stoichiometry (but not exact because aluminium andphosphate can form many different chemical materials) is: 2 PO43- + Al2(SO4)3  2 AlPO4 + 3 SO42- If the concentration of phosphate (PO43-) is 30 mg/L, how many kg of alum must be purchased annually to treat 40L/s of wastewater? How many kg/yr of solid precipitate will be formed (drybasis) if all of the phosphate is...
