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.

The transition metals: overview The elements in the centre of the periodic table‚ between groups 2 and 3‚ are called the transition metals. Most of the commonly used metals are there‚ including iron‚ copper‚ silver and gold The transition metals Common properties The transition metals have the following properties in common: they

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
