Silver ion reacts with chloride ion to form insoluble AgClAluminum ion does not form a precipitate when reacted with chloride ionsLead (II) ion reacts with chloride ion to form insoluble PbCl2PbCl2 is soluble in hot water whereas AgCl is notUse this information to outline a procedure that would determine whether Ag+ , Pb2+ , or Al3+ is present in an unknown that contains one, and only one, of these three ionsThank you!
It comes from the moisture in your shower or bathThe moisture sticks to surfaces and any dust that might be happening then stick to the moisture.
Regarding my question about aluminum siding, I just wanted to let you know that the house is 1100 square feet and located in a suburb of a major city of OhioI'm sorry to contact you this way, but I don't have e-mail contact enabled.
Dust in the my bathroom comes from towels, carpetsAlso dust from hair and skin cells and dust accumulates to in places that don't have good ventilationI also have some dust from my catsI have to dust my bathroom all the time.
Is your toilet paper near the counter top? It could be lint from the toilet paper or a box of tissues, maybeAlso, it is a very confined area (compared to the rest of the house) and dust is from skin cellsThey just fall onto the counterAlso, if you apply powder makeup near the counter, it could get all over it! Another reason is that your air ducts or the fan in your bathroom could need to be cleaned and every time they are in use they spew out dust! Once you find the source, then you will know how to treat it! Good luck!
You have a distinguishing characteristic for each metal compound, so here is a combination of differentiating steps: 1) Dissolve your unknown in acid2) Add sodium chloride solution dropwiseObserve to see if a cloudy precipitate forms when you add the salt solutionIf it does, you have Pb or Ag, the aluminum does not form an insoluble precipitateIf no precipitate, it's Al3) If the precipitate forms, continue to add salt solution until no more precipitate forms4) Filter the solution through a filter paper to separate the precipitate5) Wash the precipitate in hot water through the filter paperIf it is retained on the filter paper, it is AgClIf it dissolves and goes through the filter paper, it is PbCl2.
