Silver Mirror Experiment Background: This experiment was first conducted by Bernhard Tollens‚ it is used to determine whether a carbonyl containing compound is an aldehyde or a ketone. An aldehyde is a compound containing a formyl group (CHO).The experiment involves diamminesilver complex and a chemical reagent (also known as “Tollens’ reagent”) which in this case is glucose. In a successful experiment a reflective silver metal should precipitate‚ with characteristics identical to that of a mirror’

Test tube C did not mix well with the silver nitrate. The Iodine stayed at the bottom while the silver nitrate collected at the top. Test tube D did absolutely nothing‚ but get a little cloudy 5. Conclusion: The purpose of this lab was to see how silver nitrate affects the reactive Halogens and to see if it formed a precipitate. Most results were the same where a precipitate formed. Some took longer than others to form where as others had no effect to the silver nitrate. Two ways to improve the lab

with silver nitrate solution of known concentration. Silver ions form insoluble silver chloride when added to a solution containing chloride ions: Ag+(aq) + Cl-(aq) -> AgCl(s) By adding silver ions until silver chloride is no longer precipitated‚ the amount of chloride in a solution can be found. Potassium chromate (VI)‚ K2CrO4‚ can be used to indicate the end-point of the titration‚ the point at which all chloride ions have been precipitated. Silver ions

Silver Linings Playbook Essay Jason Lin Camden County College Pat the main character of the movie has bipolar disorder. Bipolar Disorder is also known as Manic Depressive Disorder. Bipolar Disorder consists of mood swings from the lows of depression to the highs of mania. These mood swings may happen as often as a few times a day to a few times a year. The exact cause of Bipolar Disorder is still unknown. Since the exact cause of Bipolar Disorder is unknown it is unknown what

When you mix copper‚ silver‚ and nitrate together‚ you will end up with silver nitrate solution will turn blue (it has become copper nitrate). On the piece of copper‚ there would be a coating of solid silver. If a chemical reaction is going to be observed when chemicals are mixed‚ heated or any other means of altering the substance‚ then we will be able to predict the products formed. If it is observed that in the original versus the changed substance no new substances are formed‚ the change is reversible

the mass of one product. Purpose: The experiment will be designed to find out the stoichiometric mole ratio of Barium Chloride and Silver Nitrate yielding a precipitate of Silver Chloride in a Barium Nitrate solution. (BaCl2 + 2AgNO3 -> Ba(NO3)2 + 2AgCl) Research Question: How will the amount of Barium Chloride and Silver Nitrate affect how much Silver Chloride is produced? Hypothesis: If there is one mole of BaCl2 in the reaction‚ then two moles of AgCl will be produced. Variables:
