We all do dumb things now and then, and computer users are no exception. Inadvertently pressing the wrong key combination or innocently clicking OK in the wrong dialog box can change important settings that alter a computer's behavior or even crash the system.
Lead(II) chloride (PbCl 2) is an inorganic compound which is a white solid under ambient conditions. It is poorly soluble in water.Lead(II) chloride is one of the most important lead-based reagents. It also occurs naturally in the form of the mineral cotunnite.ead(II) chloride (PbCl 2) is an inorganic compound which is a white solid under ambient conditions. It is poorly soluble in water.
Chlorides are soluble in water with the exception of silver, lead and mercury. This means PbCl 2 is insoluble and form a precipitate. The finished reaction is: 2 KCl(aq) + Pb(NO 3) 2 (aq) â 2 KNO 3 (aq) + PbCl 2 (s).The solubility rules are a useful guideline to predict whether a compound will dissolve or form a precipitate.ccording to the solubility rules, all silver salts are insoluble in water with the exception of silver nitrate, silver acetate and silver sulfate. Therefore, AgBr will precipitate out. The other compound Mg(NO 3) 2 will remain in solution because all nitrates, (NO 3) - , are soluble in water.
