Unformatted text preview: KI NG FAHD UNI VERSI TY OF PETROLEUM & MI NERALS CHEMI STRY DEPARTMENT EXPERIMENTS IN PHYSICAL CHEMISTRY CHEM-311 Prepared For Dr.Hwang EXP # 7 kinetics of cane sugar (sucrose) inversion DONE BY: Al-Juhani, Abdul-Rahman s . ID# 945826 SEC.#: 52 Date Of Performance: 26/10/97 Date Of Submission: 2/11/97 INTRODUCTION I-Objective:--To obtain the specific rotation of sucrose.-To obtain the order and rate constant of the hydrolysis reaction of sucrose. II-Theory:- The specific rotation is expressed as [ ] where is the angle through which the plane of rotated by a column of solution 100 mm in length, containing 1g of substance per cm 3 at 20 C. If the rotation is consumed to be proportional to the concentration, C, then: [ ] 20 o C C = In this experiment we study the kinetics of:- Sucrose Glu e Fructose C H O H O H C H O C H O H 12 22 11 2 6 12 6 6 12 6 + + + + + + cos Cane sugar is dextro-rotatory, but the mixture of glucose and fructose resulting from inversion is leavo-rotatory. So, the decrease in fructose resulting from inversion is leavo-rotatory....
