Conductivity Tests of Common Solutions

The video tutorial explores the conductivity of various solutions, including distilled water, tap water, vinegar, table sugar, table salt, and baking soda. The instructor tests each solution using a battery and light bulb setup to observe conductivity. Notable reactions include bubbles forming in tap water, table salt, and baking soda solutions, indicating conductivity. The video provides a practical demonstration of how different substances affect electrical conductivity.
