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.
For instance, if you add Cl-ions to a solution with this equation, it will react to form more PbCl2(s). Or if you add PbCl2(s) it will react to form more Pb2+ and Cl-. The reason that it is less soluable in HCl, is because in water HCl breaks up into H+ and Cl-.Therefore if you have or add HCl, it is like you are adding Cl-. According to Le Chatliers principle this will react to form more PbCl2(s).Therefore not as much of it will dissolve.he reason that it is less soluable in HCl, is because in water HCl breaks up into H+ and Cl-.
