Many substances will dissolve in water, which is often called the 'universal solvent'. Salts, sugars, acids, alkalis, and some gases, like carbon dioxide, are soluble in water. The key factor determining solubility is the polarity of the molecules involved. Polar substances tend to dissolve well in water, making it an ideal medium for many chemical reactions and solutions needed in daily life, cooking, and various industrial processes.
FAQs & Answers
- Why is water called the universal solvent? Water is called the universal solvent because it can dissolve many substances due to its polar molecule structure, enabling it to interact with various polar and ionic compounds effectively.
- What kinds of substances dissolve best in water? Polar substances such as salts, sugars, acids, alkalis, and some gases like carbon dioxide dissolve best in water because of its polarity.
- How does molecular polarity affect solubility in water? Molecular polarity affects solubility because polar water molecules attract and surround polar solutes, allowing them to break apart and dissolve easily.
