Detailed explanation-1: -Water’s polarity allows it to dissolve other polar substances very easily. When a polar substance is put in water, the positive ends of its molecules are attracted to the negative ends of the water molecules, and vice versa.
Detailed explanation-2: -Water molecules attract each other due to polarity. Polarity: Although the net charge of a water molecule is zero, water is polar because of its shape. The hydrogen ends of the molecule are positive and the oxygen end is negative. This causes water molecules to attract each other and other polar molecules.
Detailed explanation-3: -Cohesion: Hydrogen Bonds Make Water Sticky Water has an amazing ability to adhere (stick) to itself and to other substances. The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a “sticky” liquid.
Detailed explanation-4: -Generally speaking, water is good at dissolving ions and polar molecules, but poor at dissolving nonpolar molecules.
