What else can I help you with?
Can you separate potassium thiocyanate or silver nitrate from iron III chloride after they are mixed?
No, not without a lot of work if you are referring to powdered samples. In aqueous solution you would get a blood red color due to the soluble complex, [Fe(SCN)2]-, a white solid due to insoluble AgCl formation, and another white solid due to insoluble AgSCN formation. You could filter the solution and recover the silver with a bit more work . . .
How do you prepare a dry sample of silver chloride?
To prepare a dry sample of silver chloride, dissolve silver nitrate in water and add hydrochloric acid to form a white precipitate of silver chloride. Filter the precipitate, wash it with distilled water, and then dry it in an oven or desiccator to remove any remaining water.
How could you make a pure sample of solid silver chloride starting with silver nitrate solution?
Add hydrochloric acid to silver nitrate and stir well to ensure it is all reacted. Silver chloride will precipitate out and is fairly insoluble. Filter the solution and collect the filtrate on the filter paper. Rinse a few times with water to wash off the excess acid. Dry the filtrate in the oven. The result is pure silver chloride. Note this is sensitive to UV light, so this is best done in a dark room under a red lamp.
What two elements could be formed from the decomposition of barium phosphide Ba3P2?
From the decomposition of barium phosphide (Ba3P2), barium (Ba) and phosphorus (P) would be formed.
Which method could be used to obtain copper from a mixture of powdered copper and sodium chloride?
Electrolysis can be used to separate copper from a mixture of powdered copper and sodium chloride. By passing an electric current through the mixture, the copper ions will be attracted to the negative electrode (cathode) where they will be reduced and deposited as solid copper. This process will allow the separation of copper from the sodium chloride.
What method could be used to separate a mixture of barium sulphate and ammonium chloride and lead chloride?
One method to separate a mixture of barium sulfate and ammonium chloride, and lead chloride would be to use precipitation. By adding a solution of sodium sulfate (Na2SO4), barium sulfate will precipitate out due to its low solubility. The remaining solution can then be filtered to separate the lead chloride from the ammonium chloride.
How could you separate BaS04 from NaCl?
Barium sulfate is insoluble in water; after filtration remain on the filter and sodium chloride pass as a solution.
How do you separate silver chloride?
The solubility of silver chloride in water is almost negligible. So it could be separated from water by filtration or evaporation.
How could you distinguish solid barium chloride?
Solid barium chloride can be distinguished by its white crystalline appearance and its solubility in water. When barium chloride is dissolved in water, a white precipitate of barium sulfate forms upon the addition of a sulfate-containing solution, due to the formation of a precipitate (BaSO₄) that is insoluble in water.
Is barium chloride conductive?
Not in its usual solid state. But like other ionic compounds calcium chloride will conduct electricity if molten or dissolved in water.
How could you detect the presence of chloride negative ion?
One common method to detect the presence of chloride ions is through a silver nitrate solution. When silver nitrate is added to a sample containing chloride ions, a white precipitate of silver chloride forms. Another method is ion chromatography, which can separate and detect chloride ions based on their different migration times in a chromatographic column.
Can you separate potassium thiocyanate or silver nitrate from iron III chloride after they are mixed?
No, not without a lot of work if you are referring to powdered samples. In aqueous solution you would get a blood red color due to the soluble complex, [Fe(SCN)2]-, a white solid due to insoluble AgCl formation, and another white solid due to insoluble AgSCN formation. You could filter the solution and recover the silver with a bit more work . . .
How could you separate sodium chloride from water?
Water is deleted by heating and evaporation.
How could you tell the difference between an iron chloride and sodium chloride solution?
One way to differentiate between iron chloride and sodium chloride solutions is to perform a chemical test using silver nitrate. Iron chloride solution will form a white precipitate of silver chloride, while sodium chloride solution will not react with silver nitrate. Another method is to use a flame test: iron chloride imparts a yellow color to the flame, while sodium chloride does not.
How do you prepare a dry sample of silver chloride?
To prepare a dry sample of silver chloride, dissolve silver nitrate in water and add hydrochloric acid to form a white precipitate of silver chloride. Filter the precipitate, wash it with distilled water, and then dry it in an oven or desiccator to remove any remaining water.
How could separate zinc chloride from silicon oxide?
Zinc chloride is very soluble in water and silicon dioxide is not soluble. - Put the mixture of ZnCl2 and SiO2 in water - Wait for the dissolving of the ZnCl2 - Separate the two components by filtering
