Operation method of solid and liquid reagent reaction experiment

Abstract

The invention provides an operation method of a solid and liquid reagent reaction experiment. The method is characterized in that a specially-designed solid-state reagent clamping device is adopted, sampling of solid-state reagents can be controlled by virtue of the solid-state reagent clamping device by only needing simple operations of holding and loosening two clamping arms, a clamping state of the solid-state reagents can be stably maintained, so that under the consideration of a specific operation process, the solid-state reagent clamping device is mounted on a beaker mouth in which liquid-state reagents are held by virtue of support rods on the two clamping arms, and thus, the solid-state reagents and the liquid-state reagents are converged and reacted; moreover, the solid-state reagent clamping device can be taken out of a beaker anytime so as to stop the reaction, and therefore, solid-liquid separation is convenient to operate, other impurities are not introduced, the harm to operation personnel is avoided, the operation potential safety hazard is reduced, and the problems that the solid-liquid separation is difficult to operate in the solid and liquid reagent reaction experiment in the prior art, the impurities are easily introduced and the operation potential safety hazard happens are solved well.

Description

technical field [0001] The invention relates to the field of chemical experiment operation methods, in particular to a solid-liquid reagent reaction experiment operation 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 too...
