Description
Technical field
The utility model belongs to chemical field, relates to a kind of chemical experiment device, particularly for demonstrating experiment ferrous hydroxide preparing by senior chemistry textbook
.
Background technology
New textbook people teaches version chemistry 1(required) chapter 3 first segment prepares the experiment of ferrous hydroxide, tests like this in teaching material: in test tube, add a small amount of freshly prepd copperas solution, then instill sodium hydroxide solution.Can see after clamp-oning sodium hydroxide solution, precipitation becomes celadon at once, finally becomes bronzing after a while.This is that white flock precipitate becomes celadon rapidly because the ferrous iron of ferrous hydroxide is very easily oxidized to ferric iron, finally becomes ferric hydroxide russet.Therefore, the experiment existing defects in teaching material: because the ferrous iron in ferrous hydroxide is very easily oxidized to ferric iron in atmosphere, so be difficult to obtain stable ferrous hydroxide white precipitate by the method in teaching material
.
Utility model content
The utility model object is to provide a kind of experimental provision preparing ferrous hydroxide.Use the utility model can obtain stable ferrous hydroxide white precipitate.The utility model is not only suitable on classroom and does lecture experiment, is also suitable for student and does grouping experiment
.
The purpose of this utility model realizes by the following method:
Prepare an experimental provision for ferrous hydroxide, be primarily characterized in that: it is made up of the iron stand (1) with iron clamp (2), 90 ° of glass tubes (3), rubber stopper (4), short-range missile tracheae (5), spring clamp (6), emulsion tube (7), syringes (8)
.
Iron stand (1) is fixed 90 ° of glass tubes (3), and upward, a mouth of pipe is towards the right side for a mouth of pipe of 90 ° of glass tubes (3).Rubber stopper (4) jam-pack 90 ° of glass tubes (3) of band short-range missile tracheae (5), towards the mouth of pipe on the right side, are with the emulsion tube (7) of spring clamp (6) connect the short-range missile tracheae (5) of rubber stopper (4) outer end and the syringe (8) of brand-new copperas solution is housed.In 90 ° of glass tubes (3), the sodium hydroxide solution and vegetable oil that boiled are housed
.
realtest process: connect instrument, the impermeability of testing fixture.With iron clamp (2), 90 ° of glass tubes (3) are fixed on iron stand (1), make a mouth of pipe of 90 ° of glass tubes (3) upward, a mouth of pipe towards the right side, with rubber stopper (4) jam-pack 90 ° of glass tubes (3) of band short-range missile tracheae (5) towards the mouth of pipe on the right side.Draw appropriate brand-new copperas solution with syringe (8), then connect the short-range missile tracheae (5) of rubber stopper (4) outer end with the emulsion tube (7) of band spring clamp (6) and the syringe (8) of brand-new copperas solution is housed.Fastening spring folder (6), toward 90 ° of glass tubes (3), the sodium hydroxide solution boiled in right amount is added from 90 ° of glass tubes (3) mouth of pipe upward, then drip several vegetable oil on the sodium hydroxide solution surface of boiling, make the sodium hydroxide solution in 90 ° of glass tubes (3) completely cut off air.During experiment, open spring clamp (6), touch syringe (8), after allowing the brand-new copperas solution in syringe (8) enter in 90 ° of glass tubes (3) to mix with the sodium hydroxide solution boiled, fastening spring presss from both sides (6), at this moment can see, produce white precipitate in 90 ° of glass tubes (3), and white precipitate is long placed in nondiscolouring.This is because, ferric ion is not had in brand-new ferrous sulphate, only has ferrous ion, the oxygen-free gas of the sodium hydroxide solution boiled, there occurs chemical reaction when brand-new copperas solution enters and mixes with the sodium hydroxide solution boiled in 90 ° of glass tubes (3) in the syringe (8) to generate white ferrous hydroxide and precipitate, again because the sodium hydroxide solution surface coverage of boiling one deck vegetable oil in 90 ° of glass tubes (3), all do not contact with oxygen in course of reaction and after reaction, so the ferrous hydroxide generated can not be oxidized, thus stable white ferrous hydroxide can be obtained
.
The beneficial effects of the utility model are: device is simple, easy to use, phenomenon is obvious; Use the utility model can prepare stable ferrous hydroxide white precipitate; The utility model is not only applicable to classroom does lecture experiment, is also applicable to student and does grouping experiment.

Embodiment
Below in conjunction with embodiment, the utility model is described in further detail:
Prepare an experimental provision for ferrous hydroxide, be primarily characterized in that: it is made up of the iron stand (1) with iron clamp (2), 90 ° of glass tubes (3), rubber stopper (4), short-range missile tracheae (5), spring clamp (6), emulsion tube (7), syringes (8)
.
Iron stand (1) is fixed 90 ° of glass tubes (3), and upward, a mouth of pipe is towards the right side for a mouth of pipe of 90 ° of glass tubes (3).Rubber stopper (4) jam-pack 90 ° of glass tubes (3) of band short-range missile tracheae (5), towards the mouth of pipe on the right side, are with the emulsion tube (7) of spring clamp (6) connect the short-range missile tracheae (5) of rubber stopper (4) outer end and the syringe (8) of brand-new copperas solution is housed.In 90 ° of glass tubes (3), the sodium hydroxide solution and vegetable oil that boiled are housed
