1.检验水的微弱导电性。 实验目的:检验水的导电性,证明水是极弱电解质。 仪器装置制作:取一个日光灯用启辉器,剥除铝质外壳及去掉其中纸质电容器后,把它接在一个破灯泡头(小心敲去玻璃,留灯头、玻璃柱及两根金属丝)的两根金属丝上。将15W灯泡取下,换插上上述日光灯启辉器,构成导电实验装置。 演示法:取一小烧杯,盛约50毫升蒸馏水,将此导电实验装置之电极插入蒸馏水中,接
1. Verify the weak conductivity of water. Purpose of the experiment: Test the conductivity of water and prove that water is a very weak electrolyte. Equipment Installation: Take a fluorescent lamp starter, strip the aluminum shell and remove the paper capacitor, and connect it to a broken bulb head (be careful to knock off the glass, leave the lamp cap, glass column and two wires) On the two wires. The 15W bulb was removed and the fluorescent lamp starter was plugged in to form a conductive experiment device. Demonstration method: Take a small beaker and hold approximately 50 ml of distilled water. Insert the electrode of this conductive test device into distilled water.
