    A KINETIC STUDY OF AN IODINE CLOCK REACTION PURPOSE To investigate the kinetics of the reaction that occurs between iodide and persulfate ion. You will: (1) determine the rate law‚ (2) determine the numerical value of the rate constant at room temperature‚ (3) explore the effect of temperature on the reaction and determine the activation energy (Ea)‚ and (4) investigate catalytic activity of selected metal ions on the reaction. INTRODUCTION Reaction times vary from picoseconds (10-12 seconds)

    In this lab‚ the pH of flat sprite and a fresh sprite are compared two ways: one way was to record the pH directly with a digital pH probe and the other was to calculate the concentration through titration. Because the reaction is a neutralization reaction‚ the concentration of can be calculated if the concentration of is known. At the end of the titration‚ the moles of will equal the moles of and the pH is expected to be greater than 7 because the found in sprite is weak and is a strong

    was soluble in water as well‚ but it had a very low melting point. All the substances except for sodium carbonate did not pass the requirements‚ and therefore sodium carbonate is the best possible substance. In order to prove this‚ I conducted a lab to determine the solubility‚ conductivity‚ and melting point of each substance. First‚ I made sure to obtain a Bunsen burner‚ evaporating dish‚ ethanol‚ the four substances‚ distilled water‚ conductivity probe‚ wash bottles‚ test tubes‚ and a beaker

    AP Chemistry Chapter 13 Outline Condensed phases: the liquid and solid phases; phases in which particles interact strongly. 13.1 Gas condensed when cooled and compressed. In the liquid state the forces of attraction among particles are great enough that disordered clustering occurs. It is hard to compress a liquid. Liquids diffuse into other liquids with which they are misicible. The natural diffusion rate is slow at normal temperatures. Cooling a liquid lowers its molecular kinetic energy
