Title: Experiment 17‚ Reaction kinetics – Determination of the activation energy of the reaction between oxalic acid and potassium permanganate. Objective: To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Introduction: Chemical kinetics is the study of chemical reaction rates‚ how reaction rates are controlled and the pathway or mechanism by which a reaction proceeds from its reactants to its products. Reaction rates vary from the very fast‚ which

The Synthesis and Determination of Empirical Formula for Magnesium Oxide Aim: To determine the empirical formula for magnesium oxide. Data Collection: Table 1 Mass of empty crucible‚ crucible + Mg (roughly 1cm pieces of a 15-cm piece of magnesium ribbon)‚ and crucible +MgxOy. (mass measured with an analytical balance). The mass of crucible + MgxOy was obtained after a continuous process of heating‚ letting cool‚ heating with water enough to immerse the content and letting cool of the Mg. Mass

DETERMINATION OF ABCESSION SIZE USING DIGITAL IMAGE PROCESSING TO AIDE ENDODONTIC THERAPY Karthikeyan Karunakaran‚ Nikil Ravi‚ Srinevasan MS Abstract-- Endodontic therapy is a treatment where the infected tooth s cavity is removed completely and filled with gutta-percha .During this therapy the size of the abscission in the root apex is important. If the abscission size is small the dentists call them lesion which can be easily removed during the therapy itself. But if it is large‚ the therapy

RECRYSTALLIZATION AND MELTING POINT DETERMINATION OF BENZOIC ACID ANSWERS TO QUESTIONS 1. How does the use of fluted filter paper hasten filtration? Why is it advisable to place a small piece of wire between the funnel and the mouth of the flask during hot filtration? Fluted filter paper is effective in preventing crystal formation in the filter paper. It is also often used in filtering hot saturated solution used during crystallization. One major advantage of a fluted filter is that it increases

Experiment18 Aim To determination the partition coefficient of ethanoic acid between water and butan-2-ol. Procedure 1. The room temperature was recorded. 2. 15cm3 of the given aqueous ethanoic acid and 15cm3 of butan-2-ol were poured into a 100cm3 separating funnel‚ using suitable apparatus. The funnel was stoppered and was shook vigorously for 1 to 2 minutes. (The pressure in the funnel was released by occasionally opening the tap.) 3. 10cm3 of each layer was separated
