Abstract

本发明模拟雷电法合成一氧化氮演示仪,包括试管、中央电极、梳状电极、塞子、按键和高压模块组成,所述梳状电极上有一个个尖锐的突起。所述中央电极、梳状电极采用的材料为金属铜。使用时,按下按键高压模块给中央电极和梳状电极供电,在中央电极和梳状电极之间形成高压,梳状电极的突起和中央电极之间放电,起到模拟雷电的效果,成一氧化氮。由于一氧化氮化学性质非常活泼,与试管中的氧气发生发应生成红棕色的二氧化氮。从而根据颜色的变化达到模拟雷电合成一氧化氮的目的。

Description

模拟雷电法合成一氧化氮演示仪
技术领域
本发明涉及一种教学仪器,特别涉及一种化学仪器。
背景技术
在高中化学教材中提到,雷电可以使氧气和氮气发生发应生成一氧化氮,在实际教学过程中不能直观模拟,让学生有深刻印象。
发明内容
本发明要解决的技术问题是通过直观模拟,让学生看到实验现象,形成深刻印象。
为解决上述技术问题,本发明模拟雷电法合成一氧化氮演示仪,包括试管、中央电极、梳状电极、塞子、按键和高压模块组成,所述梳状电极上有一个个尖锐的突起。所述中央电极、梳状电极采用的材料为金属铜。
使用时,按下按键高压模块给中央电极和梳状电极供电,在中央电极和梳状电极之间形成高压,梳状电极的突起和中央电极之间放电,起到模拟雷电的效果,成一氧化氮。由于一氧化氮化学性质非常活泼,与试管中的氧气发生发应生成红棕色的二氧化氮。从而根据颜色的变化达到模拟雷电合成一氧化氮的目的。
本发明设计科学、使用方便,能够方便进行演示实验,提高学生的学习兴趣,具有较高的推广价值。
附图说明
图1 为本发明的结构示意图。
图中,1-试管 ,2-中央电极 ,3-梳状电极 ,4-塞子 ,5-按键,6-高压模块。
具体实施方式
参照附图并举实施例,对本发明进一步详细说明。
如图1,本发明模拟雷电法合成一氧化氮演示仪,包括试管1、中央电极2、梳状电极3、塞子4、按键5和高压模块6组成,所述梳状电极3上有一个个尖锐的突起。所述中央电极2、梳状电极3采用的材料为金属铜。
高压模块6能给整个装置提供高压电,按键5能闭合或者断开整个电路,中央电极2在试管1的中央部位,梳状电极3靠近试管壁,试管口用塞子4封闭,塞子4采用绝缘材料。
使用时,按下按键5高压模块6给中央电极2和梳状电极3供电,在中央电极2和梳状电极3之间形成高压,梳状电极3的突起和中央电极2之间放电,起到模拟雷电的效果,生成一氧化氮。由于一氧化氮化学性质非常活泼,与试管1中的氧气发生发应生成红棕色的二氧化氮。从而根据颜色的变化达到模拟雷电合成一氧化氮的目的。
