The invention provides a solid-phase chemical reaction characteristic demonstration device with continuous voltage regulation. The device is a chemical experiment demonstration instrument which can demonstrate the control effect of a solid-phase chemical reaction by external temperature and pressure. The demonstration device is formed by a bottom plate, a fixed vertical column, a horizontal pressing bar, a horizontal connection bar, a rider, a weight, an electrical conduction pool component, a temperature control component, an arc scale and an angle pointer. The fixed vertical column, the horizontal pressing bar, the horizontal connection bar and a measure electrode cathode are connected through movable rotation shafts to form a parallelogram structure, by using the rider and the weight on the horizontal pressing bar, the external pressure of a solid-phase complex can be changed continuously, by using the angle pointer and the arc scale on the horizontal pressing bar, the volume change degree of the solid-phase complex in a chemical reaction is easily calculated, the cost is low, and the presentation is intuitive.
Description
Technical field [0001] The invention relates to a chemical experiment demonstration instrument, in particular to a solid phase chemical reaction characteristic demonstration device, belonging to the technical field of chemical experiment demonstration instruments. Background technique [0002] At present, in the teaching of chemical experiment courses, when teaching the solid-phase reaction characteristics and the reaction of external temperature and external pressure factors to the solid-phase complex and the reaction speed, there is no demonstration instrument demonstration, and students cannot intuitively understand the effect of temperature and pressure on solids. The control effect of the phase chemical reaction is abstract, boring, and poor in intuitiveness. Summary of the invention [0003] The purpose of the present invention is to provide a solid-phase chemical reaction characteristic demonstration device that can continuously adjust the pressure, which can demonstrate th...
