Here's why:
* Polarity: Water molecules have a bent shape with oxygen being slightly negatively charged and hydrogen being slightly positively charged. This uneven distribution of charge creates a dipole moment, making water a polar molecule.
* Attraction: The positive ends of water molecules are attracted to the negative ends of other polar molecules (like sugars, salts, and alcohols), and vice versa. This attraction helps to break apart the solute molecules and dissolve them in water.
* Hydrogen Bonding: Water molecules can form hydrogen bonds with each other and with other polar molecules. These bonds are strong and help to keep the dissolved substances in solution.
In contrast, non-polar molecules (like oils and fats) don't readily dissolve in water because they lack the polar nature to interact with the water molecules.
