the same experiments but with temperature changes one can determine how k is affected by temperature changes and the new activation energy. Also‚ from graphs the activation energy was determined to be 33.3 kJ/mol. INTRODUCTION: The rate of a chemical reaction often depends on reactant concentrations‚ temperature‚ and the presence of a catalyst. Additionally‚ the rate law is determined mathematically only from experimental data. The reaction investigated in this experiment is: 2I-(aq) + H2O2(aq)

proceed to discuss the characteristics and services provided by her chosen chemical dependency program. It is her belief that a substance abuser and/or addict is more likely to succeed at living a life free of alcohol and drugs when they continually attend a 12-step program‚ follow the steps‚ have a sponsor‚ a support group and educate themselves on how to live life without turning to alcohol or drugs. Of the several chemical dependency programs available‚ she chose to conduct a telephone interview

the unknown sample. Since the hardness of water arises from the presence of metal ions‚ we can use disodium salt of EDTA and the indicator Eriochrome Black T to determine the concentration of M 2+ ( Mg 2+ or Ca 2+) metal ion impurities. Chemical principle or theory involved in this lab: To determine waters hardness we will use a technique called a chelometric titration. “When a neutral molecule or anion (lewis base) donates electron pairs and attaches itself to a metal ion center (a

Complexometric Determination of Water Hardness Lab Report Introduction: In this lab the use of disodium salt of EDTA is used to determine the concentration of M^2+ metal ion impurities in hard water by chelometric titration. The indicator Eriochrome Black T will help detect when you EDTA has completely chelated the metal impurities. Chemical Principle: A complex ion consists of a metal ion with Lewis bases attached to it. These Bases form strong covalent bonds with the central complex
