0 views
Substances that are soluble in water include table salt (sodium chloride), various sugars like glucose, gases such as oxygen and carbon dioxide (under certain conditions), and ethanol. Water's polarity allows it to dissolve ionic compounds well, like salts, and polar molecules, such as sugars and certain alcohols. Solubility can vary with temperature and pressure, especially for gases, with higher temperatures generally decreasing gas solubility in water. Knowing which substances dissolve in water is essential for understanding various chemical, cooking, and even cleaning processes.
FAQs & Answers
- What types of substances dissolve best in water? Ionic compounds like salts and polar molecules such as sugars and certain alcohols dissolve well in water due to its polarity.
- How does temperature affect the solubility of gases in water? Increasing temperature generally decreases the solubility of gases like oxygen and carbon dioxide in water.
- Is ethanol soluble in water? Yes, ethanol is soluble in water because it is a polar molecule that can form hydrogen bonds with water.
