Embodiment Construction

[0021] The invention provides a kind of solid-liquid reagent reaction experimental method, and this method specifically comprises the following steps:

[0022] 1) Prepare the solid reagents and liquid reagents that need to participate in the reaction, as well as a beaker and a solid reagent holding device. In the method of the present invention, a special solid reagent holding device is adopted, such as figure 1 As shown, the solid reagent holding device has two elongated support arms 10 with the same length, one end of the two support arms 10 is rotatably connected together, and the middle parts of the two support arms 10 are abutted against a compression spring 20, the ends of the other ends of the two support arms 10 are respectively fixedly connected with a vertical extension arm 30, and the two vertical extension arms 30 are respectively vertically connected to the same side of the two support arms and have the same length, and the two vertical extension arms 30 are far a...

Abstract

The invention provides a solid-liquid reagent reaction experiment method which is characterized in that a specially-designed solid reagent clamping device is adopted, and only through the simple operation of pinching and releasing two supporting arms, the solid reagent clamping device can be controlled to sample the solid reagent and stably keep clamping the solid reagent; therefore, in combination with the specific operating process, the solid reagent clamping device is erected over the mouth of a beaker holding liquid reagent through the supporting arms and stretching sliding rods, so that the solid reagent and the liquid reagent can be in contact with each other and react, and the solid reagent clamping device can taken away from the beaker to stop the reaction at any time. The method has the advantages that the solid-liquid separation operation is very convenient, other impurities cannot be brought in, the probability of damage to operators is low, the potential safety hazards of operation can be reduced, and the problems that solid-liquid separation is troublesome, impurities are easily brought in, potential safety hazards of operation exist in a solid-liquid reagent chemical reaction experiment in the prior art can be well solved.

Description

technical field [0001] The invention relates to the field of chemical experiment operation methods, in particular to a solid-liquid reagent reaction experimental method. Background technique [0002] Chemical reagents are commonly used items in chemistry laboratories and chemistry teaching. In the process of chemical experiments and chemistry teaching, it is often encountered in the operation steps that require the use of solid reagents and liquid reagents for chemical reactions. In many cases, it is even necessary to separate the solid and liquid reagents at different stages of the reaction between the solid and liquid reagents and suspend the reaction. Process, in order to observe the different states of solid reagents or / and liquid reagents in each reaction stage, or perform operations such as sampling reagents, so as to learn and analyze the chemical reaction process. However, in response to such a situation, due to the lack of special experimental operation tools, in t...
