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

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 %

Aluminum sulfate, known as cake alum, has a remarkably wide range of uses, from dyeing leather and cloth to purifying sewage. In aqueous solution, it reacts with base to form a white precipitate. (a) Write balanced total and net ionic equations for its reaction with aqueous NaOH. (Type your answer using the format (NH4)2CO3 for (NH4)2CO3, [NH4]+ for NH4+, and [Ni(CN)4]2- for Ni(CN)42-. Use the lowest possible coefficients. Type the cation before the anion.) (b) What mass of precipitate forms...

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...
