6/12/2012 - Synthesis of Silver Iodide
One of my fellow chemists asked me if I knew where she could purchase a single silver iodide crystal, and after a while searching without an answer I looked up the synthesis of this metal compound. The procedure is fairly simple starting with dissolving silver nitrate (AgNO3) in water, followed with the addition of potassium iodide (KI). A yellow precipitate will form immediately containing both the α-AgI and the β-AgI crystals which can be separated through different dissolution methods.

The casino takes its €50 fee (5%) so the banker now has €1950 and so as to to} proceed as banker should stake this whole quantity. In the second coup the bets total only €1600, so the croupier saves the remaining €350 for participant A. The financial institution wins again, and the casino takes its €80 fee and A's next financial institution must be at least of|no less than} €3120. It cannot be less, but participant A may add some of the the} €350 that the croupier has reserved to make it larger. Player A decides to SM카지노 proceed with a financial institution of just €3120 and this time the entire financial institution is covered by players' bets.
