Description
Technical field
The utility model relates to a kind of teaching and experimental demonstration device, specifically a kind of apparatus for demonstrating for verifying concentrated sulphuric acid strong oxidizing property.
Background technology
The concentrated sulphuric acid, is commonly called as bad water, and chemical molecular formula is H2SO4, is a kind of strong mineral acid with highly corrosive.Bad water refers to that massfraction is more than or equal to the sulfuric acid solution of 70%.The concentrated sulphuric acid has strong oxidizing property when concentration height, and this is one of maximum difference of it and common sulfuric acid or the common concentrated sulphuric acid.It also has dehydration property, strong oxidizing property, severe corrosive, difficult volatility simultaneously, acid, stability, water absorptivity etc.In the study of middle chemistry course, the character of its concentrated sulphuric acid is important content, need the demonstration test of carrying out concentrated sulphuric acid characteristic under the guidance of teacher, student also can be allowed to carry out the operation of demonstration test in person, because the concentrated sulphuric acid has very strong corrosivity, if be splash on skin or clothes because of carelessness during experiment, process can cause certain injury not in time, therefore when learning this content, generally that teacher carries out suggestion and gives lessons while operate and carry out demonstration test, and be all generally carry out emphasis to the test of concentrated sulphuric acid dehydration property tell about and verify when learning, and the checking of other characteristics of the concentrated sulphuric acid, generally consider the shortage of danger or experimental apparatus, there is no apparatus targetedly, usually just explained by experiment description simple on textbook, student is made to add difficulty on understanding and cognition, reduce the efficiency of giving lessons of teacher, use inconvenience.
Summary of the invention
For the problems referred to above, the utility model provides a kind of apparatus for demonstrating for verifying concentrated sulphuric acid strong oxidizing property, solve teacher and worry that student easily causes danger in concentrated sulphuric acid strong oxidizing property experimental demonstration process, and just explained by experiment description simple on textbook, make student add difficulty on understanding and cognition, reduce the problem of the efficiency of giving lessons of teacher.
For achieving the above object, the technical solution of the utility model is specific as follows:
For verifying an apparatus for demonstrating for concentrated sulphuric acid strong oxidizing property, comprise reaction chamber 1, feeding pipe 6, sulfuric acid pipe 3, base 7, waste collection bottle 8, support 10, it is characterized in that: described reaction chamber 1 is arranged on base 7 by support 10, the one end on described reaction chamber 1 top arranges feeding pipe 6, the other end arranges sulfuric acid pipe 3, the bottom of described reaction chamber 1 is specially wedge structure, and outlet is connected with waste collection bottle 8 by connecting pipe, and described connecting pipe and waste collection bottle 8 junction arrange valve 9, described feeding pipe 6, its upper end arranges feeding mouth 2, lower end is extended in reaction chamber 1, and it is corresponding with the outlet of the bottom of reaction chamber 1, the centre position of described feeding pipe 6 is arranged holds feed collet 5, described sulfuric acid pipe 3 arranges valve I 4, and its one end is extended in reaction chamber 1.
Wherein for verifying an apparatus for demonstrating for concentrated sulphuric acid strong oxidizing property, described reaction chamber 1 is specially clear glass.
The beneficial effects of the utility model are:
The utility model structure is simple, easy to use, easy to operate, easy to use, easy to operate, facilitate the demonstration of concentrated sulphuric acid strong oxidizing property, improve the efficiency of giving lessons of teacher, enhance the understanding and cognition of student to knowledge point, easy to use, solve teacher and worry that student easily causes danger in concentrated sulphuric acid strong oxidizing property experimental demonstration process, and just explained by experiment description simple on textbook, student is made to add difficulty on understanding and cognition, reduce the problem of the efficiency of giving lessons of teacher, hold the setting of feed collet 5, be conducive to clamping magnesium rod, and magnesium rod is experimentally needed to stretch in reaction chamber 1 by feeding pipe 6, the setting of waste collection bottle 8, is conducive to the waste liquid after confirmatory experiment and collects, practical safe and reliable.
