Demonstrating the Tollens' test for aldehydes and reducing sugars. The silver deposit forms a mirror-like coating on the inside of the reaction vessel. You can find instructions for this experiment at www.rsc.org/learn-chemistry/re....
2Na2SO3 + 4AgNO3 --> 2Ag + Ag2SO4 + SO2 + 4NaNO3 This can be also done, but make sure to heat test tube without boiling the solution... This is reaction for identifying SO3 2- ions in the solution :)
Yes and yes. But the last is depending on the air quality where you live since the silver will tarnish from nitrate compounds from cars and such so if you life close to a trafficated road or in the middle of a a city the tarnish will get faster then if you would live at a calm riverside in the middle of nowhere. I might ad though that the tarnish of the mirror in the middle of a city/trafficated road won't exactly happen over the night it will take time but it will happen sooner or later depending on the air.
75 cc from 0.8M of KOH or NaOH ? Nice video... How many cc finally used about Ammonia? 5 cc when you added Ammonia to Silver SOlution, then when you added OH- how many ?
