Question

health effect. 8. (10 pt) Glutamic acid (CH,O.N) is used as one of the reagents for a standard to check the BOD test. Determine the theoretical oxygen demand of 63 mg/L of Glutamic acid. Assume the following reaction apply: CH,ON +4.5 0. + 5 CO,+ 3H2O + NH, NH, + 20 ► NO, + H + H2O I 3 А

Answer 1

Cg Hg OqN +4.50 +500 2 + 3H₂O + NH3 NH₃ +202 + NO +ht +H₂O combining both Reactions a CG Hg Oq N + 6.50 +5202 + 4H₂0 THT + NO3 #molecules weight of Glutamic acid = 5x12+ 9x1 + 4x16+ 14 = 147gm e For complete Reaction a I mole of Cg Hg ay n requires 6.5 mole o 147gm of lig Hg Oy No requires (6.5X32= 208gm) orygen 1 gm CG Hg Dun 208 147 monggen 63 mg/L CG Hg Own e 208 x63 .X 63 nghe onlygen 89.14 mg/L onggen 147 so Theoritical orygen demand 189.14 mg IL
