the element Silver (Ag) which was first mixed with chloride (Cl). Together the two mixtures created a very white‚ milky type which is known by the name of Silver Chloride (AgCl). Iodine (I) was then mixed with silver to create a yellowish‚ whitish color which is normally called Silver Iodine (AgI). The mixture followed is Silver Oxide (Ag2O) which happens to contain hydroxide (OH) as well a silver. This compound ended up turning a very grey-brown like color as well as being gritty.

Writers of great literature seek to explore the various aspects of the human condition; Cormac McCarthy is no different. McCarthy seamlessly interweaves philosophical discussion with the narrative of his novels; he addresses numerous questions that we‚ as thinking beings‚ ultimately and ceaselessly ask ourselves. He examines concepts such as morality‚ religion‚ and justice; he “appears to believe that such ultimate questions . . . haunt us for the simple reason that we cannot answer them with anything

BSc Pharmaceutical Technology Practical - No 5 Preparation of a Primary Standard Solution Aim: to prepare a standard solution of pure silver nitrate and use it to determine the concentration of chloride ions in a sample of tap water and another sample of bottled water. Chemicals: * High grade purity silver nitrate * Potassium chromate indicator * Tap water * Bottled water * Distilled water Apparatus: * Laboratory oven * Dessicator * Conical flask

solubility differences of two anions and the titration endpoint of a precipitate. The net ionic reaction during the titration is as follows: Ag+ + Cl- → AgCl(s) The Ksp for AgCl is 1.8 x 10-10 and that for Ag2CrO4 is 1.2 x 10-12. Thus‚ as silver ions are slowly added to solution‚ AgCl precipitates first‚ removing the chloride ions from solution. As can be inferred‚ Ag+ ions react with almost all chloride ions before precipitation of Ag2CrO4 begins. Thus‚ the secondary reaction is

Allied Chemical to manufacture one thousand containers. Allied Chemical needs the containers for storage of five kinds of aqueous nitrate solutions. The aqueous nitrates are copper (II) nitrate‚ lead (II) nitrate‚ zinc nitrate‚ magnesium nitrate‚ and silver nitrate. You can not manufacture the containers from glass due to possible breakage. Nor will plastic containers do because plastic tends to harden over time and also may shatter. This leaves metal. Unfortunately‚ many metals get eaten away
