PLANNING Investigating the Kinetics of the reaction between Iodide ions and Peroxodisulphate (VI) ions By the use of an Iodine clock reaction I hope to obtain the length of time taken for Iodine ions (in potassium iodide) to react fully with Peroxodisulphate ions (in potassium Peroxodisulphate). I will do three sets of experiments changing first the concentration of iodide ions‚ then the concentration of Peroxodisulphate ions and finally the temperature of the solution in which the reaction is

The goal for our lab activity was to make a silver mirror by reducing silver ions with dextrose. The materials that we used were acetone‚ 5 mL of 1.5 M ammonium nitrate solution (NH4NO3)‚ 5 mL of 0.5 silver nitrate solution (AgNO3)‚ 10 mL of 5% dextrose solution (C6H12O6)‚ 10mL of 10% sodium hydroxide solution (NaOH)‚ a 50 mL beaker‚ a 250 mL Florence flask with a rubber stopper‚ a 10 mL graduated cylinder‚ a waste beaker‚ and distilled water. The first thing we did was rinsed the beaker‚ cylinder

The plot of the story "The Storm" by Kate Chopin is a conventional everyday plot. The story would not be so interesting if it weren’t for the last line of the story; "So the storm passed and everyone was happy." What did she mean by the closing line? My interpretation of the story is that she meant the rocky part of both Calixta and Alcee’s marriage had passed along with the storm. Both Alcee and Calixta cheated on their spouse‚ however‚ they both knew that when the stor was over they would

Super Storm Hurricane Sandy Widespread loss of electric power and subway shutdowns the associated press reports that more than 13‚500 flights were canceled and in New York three major airports were shut down. Super storm Sandy the second most expensive storm in U.S. history‚ according to Eqecat. That ranks it right behind Hurricane Katrina. Eqecat stated that the damage from the storm would likely be far worse than it previously predicted. The storm also brought a huge economic loss by flooding

Analysis of the Protagonist “The Storm” Kate Chopin is a well known short story author from the late 1800’s who often included sexually repressed women as the protagonist in her works. One story she wrote‚ “The Storm”‚ was never submitted for publication until after her death due to the sexual nature of not only the story‚ but the protagonist as well. Calixta‚ the sexually repressed women in the short story “The Storm”‚ is a good wife and mother‚ but longs for more pleasure in her life. In

Olivia Ince “The impact of tropical storms Katrina and Nargis were beyond the scope of government to manage effectively” Discuss. Tropical storms have different names depending on their location i.e.‚ in North America and the Caribbean they are known as hurricanes whereas in India and Bangladesh they are known as cyclones. There are various factors which need to be in place for a tropical storm to occur including sea temperatures to be over 27ºC to provide a source of energy‚ warm water extending

Hydrogen peroxide and iodide ions Aim: To determine the rate equation for the reaction between Hydrogen peroxide and iodide ions‚ and to investigate the effects of a catalyst and temperatures on the reaction and to derive the activation enthalpy. Background knowledge: 1Hydrogen peroxide reacts with iodide ions producing iodine‚ when in an aqueous acid solution. H2O2 (aq) + 2I- (aq) + 2H3O+(aq) I2 (aq) + 2H2O(l) To detect iodine you can look at the color shown by the addition of starch
