    How does a catalyst in the form of a metal ion affect the rate of reaction in an iodide clock reaction with potassium peroxydisulphate ions? Background When peroxydisulfate ions (S2O82-) react with iodide ions (I-) in the presence of a starch indicator‚ they produce a dark blue solution. Reaction (1) S2O82- + 3I-  I3- + 2 SO42- (peroxydisulfate ion) (iodide ion) (iodine ion) (sulfate ion) To determine the rate law for this reaction a series of changes

    Urea is produced in the liver from excess amino acids. Where are the substances excreted? Carbon dioxide is passed from the cells of respiring tissues into the blood stream. It is transported in the blood (mostly in the form of hydrogen carbonate ions) to the lung. In the lungs the carbon dioxide diffuses into the alveoli to be excreted as we breathe out. Urea is produced by breaking down excess amino acids in the liver. This process is known as deamination. The urea is then passed through the

    What observation supports the formation of the Cu2+ ions in the solutions? The 15mL of nitric acid and the heat from the Bunsen burner supports the formation of the Cu2+ ion. Why was it important to perform this reaction in the fume hood? It is important because the chemicals produce a toxic gas. Is there any copper metal left after you have completed this step? If not‚ where is the copper? No‚ there is no copper left. It dissolved in the nitric acid solution. Did you initially observe the formation
