Abstract

The invention provides an experimental device and method for exploring the influence of the temperature on the saturation of a solution. The device comprises a supporting frame; the supporting frame comprises a placing platform and a clamping unit; an iron frame table and an alcohol lamp located below the iron frame table are arranged above the supporting frame; a beaker containing the aqueous solution is arranged on the iron frame table; a test tube and a temperature sensor are clamped on the clamping unit to be located in the beaker; the saturated solution with excess solutes is contained inthe test tube; the temperature sensor is connected to a microprocessor; and the microprocessor is connected with a display module. According to the experimental device comprising the temperature sensor, the microprocessor and the display module, an experimental process can be subjected to data processing, so that students can know the current temperature of the solution in real time, the studentshave relatively accurate concepts for temperature changes, and the experimental teaching effect is enhanced.

Description

technical field

[0001] The invention belongs to the technical field of experimental teaching equipment, and in particular relates to an experimental device and method for exploring the influence of temperature on solution saturation. Background technique

[0002] Many scientific laws will be encountered in the process of science teaching in junior high schools. Teachers usually let students learn related scientific laws through dictation, field experiments or video experiments. For example, we all know that as the temperature changes, the state of the solute in the solution will change. For a saturated solution with excess solute, heating the solution can slowly dissolve the excess solute, that is, the way of heating the solution can increase the solute in the solution. Solubility in solution. In the current teaching, teachers usually use different concentrations of salt water for experiments. For example, prepare at least two beakers with 100ml of aqueous solution at 25 de...
