Solubility and Chemical Reactions

The video introduces water as a universal solvent and demonstrates its ability to dissolve various substances through a series of experiments. Using materials from activity kits and household items, the video guides viewers through testing the solubility of sugar, salt, baking soda, and red food color in both oil and water. The results show that these substances dissolve in water but not in oil, highlighting water's unique properties. The video concludes by explaining why water can dissolve a wide range of substances, reinforcing its title as the universal solvent.
