EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

Experiment : 1 Tittle : Preparation of bis(acetylacetonato)copper(II) complex Objective : To synthesis the bis(acetylacetonato)copper(II) complex Introduction : A complex ion is usually form with high charge density metal ion as a central and formation of coordinate covalent bond (dative bond) with high electron molecules or ions. These molecules or ions are functioning as ligands (electrophile in organic compounds). They are easily attracted by electrophile (electron deficiency

Insulin pump therapy‚ commonly called continuous subcutaneous insulin infusion (CSII)‚ has increased immensely within the last decade in youth with type 1 diabetes. The giant increase can mostly be attributed to the fast acting insulin‚ insulin lispro. A few advantages of CSII in youth is the ability to ability to administer daily basal rates‚ and and the ability to use temporary basal rates. Basal insulin rates are important in controlling blood glucose levels throughout a twenty-four hour period

down my lower back. My stomach churned from the rich coffee that I drank that morning. I could feel the oxygenated blood rushing to the surface of my skin. With a beet red face and with muscles aching‚ I lifted the weights higher and higher. “Body Pump” is a specially designed class for weight lifting and cardio workout. I still remember the first time in the class; I picked up the smallest weights of two and a half pounds. I was sore with screaming muscles for the next three days. The feeling afterward

EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered
