Detailed explanation-1: -Water is called the “universal solvent” because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.
Detailed explanation-2: -Sodium chloride: Polar, and so it is soluble in water. It is transported dissolved in the plasma.
Detailed explanation-3: -It is polar, allowing for the formation of hydrogen bonds, which allow ions and other polar molecules to dissolve in water.
Detailed explanation-4: -Answer and Explanation: The four unique properties of water that make it unique are high specific heat, high polarity, adhesion cohesion, and a lower density as a solid. Water having a high specific heat allows it to absorb heat energy without a subsequent change in temperature.
