一、液體中离子移动的實驗在一個U形玻璃管的中下部裝入鲜明紫顏色的过錳酸鉀溶液,兩個支管的上部裝入無色的硝酸鉀溶液。用白金片A,B作兩極板,分別連於電池的陰、陽極。当電流通过管子的時候,我们就可以看到含有離子M_nO_4~-的有颜色的液面顯著地向陽極移動。在課堂上演示時,同学們可以看的很清楚。二、氣体电离的演示實验在1954年出版的高中物理学課本第三册第82頁上,關於氣体电离的裝置是这樣的: 这樣的裝置需要電離室和產生使氣体電离
First, the movement of ions in the liquid experiment In a U-shaped glass tube into the middle and lower sections of bright purple color of potassium permanganate solution, the upper two branches of the tube into a colorless potassium nitrate solution. With Platinum A, B for the two plates, respectively, connected to the battery cathode, anode. As current passes through the tube, we can see that the colored surface containing the ions M_nO_4 ~ moves significantly toward the anode. Students can see clearly when demonstrating in class. Second, gas ionization demonstration experiment In 1954 published high school physics textbook third book on page 82, on the gas ionization device is such: this device requires ionization chamber and produce gas ionization
